Yep, its all about how the units cancel out in this problem.
I'll give you a simple example so I can show you.
Lets say I walk at a rate of (2miles / hour), and I traveled a distance of 5 miles, how long did it take?
5 miles divided by (2 miles / hours)
if you set it up like a fraction it looks like
5mi/2mi/hr = mi cancel, hr comes out of the denominator (see fraction over fraction if this is confusing), and you get 5/2hr or 2.5 hours to walk 5 miles
One thing to remember is make sure the rate, and distance are in the same unit.
You can calculate the time it takes to travel by dividing the distance by the rate. The formula is time = distance / rate. This will give you the time in hours it takes to travel the given distance at the given rate.
The word for the rate in time and distance at which a force is produced is "power." Power is the measure of how quickly work can be done by a force, and it is calculated by multiplying force by distance divided by time.
S=d/t It's an Equation to show how to calculate the speed which would be the distance the object has traveled divided by the time is traveled for. Here's an Example: My Car traveled 10 miles in 10 hours so my speed would be 1mph as Distance: 10 miles divided by Time: 10 hours gives me 1mph.
That is called the velocity of the object. Velocity = Distance divided by Time taken.
No, the distance an object travels in unit time is called speed. The distance travelled per unit time in a specified direction is called velocity. The rate of change of velocity is called acceleration.
The formula is Distance=Rate x Time (or distance equals rate multiplied by time). When you take this into account, you can manipulate it to solve for rate or time instead of distance. In other words, you could rewrite it as Rate= Distance/Time (rate equals distance divided by time) and Time= Distance/Rate (time equals distance divided by rate) in case they ask for what the Rate or Time is instead of Distance.
Distance = Rate x Time Rate = Distance/Time, not Time/Distance
Time equals distance divided by rate.
Time equals Distance divided by rate
Rate equals Distance divided by Time.
The rate equals the distance divided by the time it takes to cover the distance. If you go 6 miles in 2 hours, the rate is 3 miles an hour.
Think of the word DISTance and you have the formula D Is S times T Distance equals Speed x Time from which you can infer that Speed equals Distance divided by Time and Time equals Distance divide by Speed So in this example How long? means find the Time, and Time = Distance/Speed which equals 960miles divided by 55mph = 17hours 27minutes 16.36363636.....seconds What about stopping for coffee or a rest?
If you take distance divided by rate you will get your time. Then if you take time by the rate you will get your distance.
rate equals distance divided by the time: example, one mile per hour would be 1 over 1. Ten miles (distance) over 1 hour (time) = 10 mph. Formula: r=d/t (rate equals distance over time)
Distance equals rate multiplied by time
You can calculate the time it takes to travel by dividing the distance by the rate. The formula is time = distance / rate. This will give you the time in hours it takes to travel the given distance at the given rate.
