a car travels 100 meters in 5 second. what is the speed of the car?

Answer 1

Simple case of distance divided by time. Important for students to determine the givens using keywords (Clues)

Distance here is a unit of measure length; essentially a "how far you went" which is 100 meters. Then we see time which has units of seconds, minutes, hours, days, weeks, months, years etc. In this case we have 5 seconds.

So d = rt

D = 100m

t- 5s

100m = (r) (5s)

we divide by 5 on both sides and we get 100m/5s yielding 20m/s

The nice part is that unit of m/s which tells us this is a rate of meters per second (m/s).

Answer 2

Distance = Rate × Time

100 = 5x → x = 20

The car will travel at the speed of 20 meters per second.
