The Mid-Atlantic Ridge is actually spreading slower than the East Pacific Rise. The rate of seafloor spreading along the Mid-Atlantic Ridge is estimated at about 2.5 centimeters per year, while the East Pacific Rise spreads at a rate of about 5 centimeters per year.
The East Pacific Rise spreads at a rate of roughly 5 centimeters per year. This spreading occurs due to tectonic plate movement, where new oceanic crust is created as magma rises up from the mantle at the mid-ocean ridges.
rate of spreading for stripe = width of stripe / time duration If a magnetic strips is 60 km wide and formed over 2 million years, then the rate at which spreading formed the was 30 km/m.y. The rate is equivalent to 3 cm/year. Spreading added an equal width of oceanic crust to a plate on the other side of the mid-ocean ridge, so the total rate of spreading across the ridge was 60 km/m.y. (6 cm/year), a typical rate of seafloor spreading.
To calculate the half sea floor spreading rate, you would divide the total spreading rate by 2. The spreading rate is typically measured in millimeters or centimeters per year and represents the rate at which tectonic plates move away from each other at a mid-ocean ridge. Calculating the half spreading rate is useful for determining the rate at which new oceanic crust is being generated on one side of a mid-ocean ridge.
Typical rates of spreading average around 5 centimeter (2 inches) per year.
The Mid-Atlantic Ridge is actually spreading slower than the East Pacific Rise. The rate of seafloor spreading along the Mid-Atlantic Ridge is estimated at about 2.5 centimeters per year, while the East Pacific Rise spreads at a rate of about 5 centimeters per year.
The Mid-Atlantic Ridge has one of the slowest rates of seafloor spreading, averaging about 2.5 cm per year. This ridge is located in the Atlantic Ocean and is less active compared to other spreading ridges like the East Pacific Rise.
The East Pacific Rise spreads at a rate of roughly 5 centimeters per year. This spreading occurs due to tectonic plate movement, where new oceanic crust is created as magma rises up from the mantle at the mid-ocean ridges.
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
The plate boundary at the East Pacific Ridge(Rise) is a diverging boundary. Ridges usually occur where two boundaries are diverging(seperating, or spreading apart, thus creating a ridge. -Textbo7
This depends at what point on Earth's surface you are interested in! For example the Mid Atlantic Ridge separating the North American and Eurasian plates is classified as a "slow" spreading centre with a spreading rate of around 25mm/yr (slow spreading centres generally have a rate of between 20-55 mm per year). This means that the North American plate is moving roughly to the west at a rate of 12.5 mm/yr. However a number of the spreading centres in the Pacific are considered to be "medium to fast" spreading centres with rates of between 80-120 mm/yr. Another example is the Indian plate which is moving north-east at a rate of approximately 50mm/yr causing it to collide with the more slowly moving Eurasian plate. This event started (and is continuing to cause) the Himalayan orogeny.
The average spreading rate for fast spreading divergent plates is typically around 5-9 centimeters per year. This rate is significantly higher than the spreading rate for slow spreading plates, which is usually less than 2.5 centimeters per year. Fast spreading plates can create oceanic ridges and lead to the formation of new oceanic crust.
The magnetic bands in the eastern Pacific Ocean are more spread out because the spreading rate of the seafloor there is slower compared to the Mid Atlantic Ridge. Slower spreading rates lead to wider magnetic bands as less new crust is being formed over a longer period of time. Conversely, faster spreading rates at the Mid Atlantic Ridge result in narrower magnetic bands due to the more rapid formation of new crust.
The Pacific region spreads 80-120 mm/yr, while the north Atlantic Ocean is just ~ 25 mm/yr.

Neither is spreading faster. They are both spreading at the same rate.
