60 km * 3 = 180 km
45 min * 4 = 180 min
180km/180hr = 1 km/min
1km = 1000m
1 min = 60s
1000m/60s = 16.67 m/s

Light travels at a rate of?
299,792,458 meters per second in vacuum
What is the speed of an object that travels 100 meters in 56 seconds?
Just divide the distance by the time. This will give you the speed in meters/second. If you want to convert that to kilometers/hour instead, multiply the result by 3.6.
What is the velocity of a bicycle in meters per second if it travels 1 kilometers west in 4.1 minutes?
1 kilometer is equal to 1000 meters. 4.1 minutes is equal to 246 seconds. Velocity would equal 1000 meters divided by 246 seconds. So the answer is 4.065 meters per second West.
Sound travels 344m in 1 second at this rate how far does sound travel in 8 seconds?
I think it must be 8 times as much. That is 2752 meters in 8 seconds.
How long does it take for light to travel one mile in microseconds?
A millionth of the distance that it travels in one second. Take the speed of light, in meters/second or kilometers/second, or even in miles/second, then divide that by a million to get the distance per microsecond.
Distance in meters that light travels in one second?
In a vacuum, light will travel 299,792,458 meters in one second.
Distance traveled by light in 1 second?
In a second, light travels about 300,000 km., or 3x108 meters.
What is the unit rate for meters per second if a car travels 437 meters in 23 seconds?
If you divide the distance by the time, you'll get the speed - in this case, in meters/second.
A wave travels an average distance of 1 meter in 1 second with a frequency of 1 hertz Its amplitude is?
A wave travels an average distance of 1 meter in 1 second with a frequency of 1 hertz Its amplitude is that there is not enough information to say. A 60 vibration per second wave travels 30 meters in 1 second, its frequency is 60 hertz and it travels 30 meters per second.
A skater increases her speed uniformly from 2.0 meters per second to 7.0 meters per second over a distance of 12 meters The magnitude of her acceleration as she travels this 12 meters is?
5.0 meters every second.
What is the speed of a proton that travels 3.021012m in 2.02104s?
Divide the distance by the time. Answer will be in meters/second in this case.
What is the unit rate for meters per second if a car travels 399 meters in 19 seconds?
Just divide the distance (in meters) by the time (in seconds).
What is the speed of a cheetah that travels a total of 112 meters in 4 seconds?
Distance = Rate * Timeso,Rate(speed) = Distance/Time= 112 meters/4 seconds= 28 meters/second
How long does it take for the suns rays toreach earth?
On average, the distance from the Sun to the Earth is about 150 million kilometers. Light travels at the speed of 299,792,458 meters/second. Doing the math, we get: (150,000,000 km x 1000) / 299,792,458 meters/second = 500.346 seconds = 8.339 minutes
If a cannon fires at a great distance from you why do you see the flash before you hear the sound.?
you see the flash of light first because light travels faster that sound. light travels at 299,792,458 meters per second whaile sound only travels at 340.29 meters per second.
