Question

The formula for distance traveled d is d=rt, where r is the average speed of the object and t is time traveled. If an object travels 30 meters in 20 seconds, what is its speed

Answer 1

Explanation:

Distance formula:

d = rt

where d = distance, r = average speed and t = time travelled.

They told us that an object travels 30 meters in 20 seconds.

So we can say d = 30 and t = 20

If you put these values back into the distance formula you get:

d = rt

30 = r times 20

30 = 20 r

So now we want to find what "r" (average speed) is.

Divide both sides by 20.

20 r = 30

r =
`(30)/(20)` = 1.5 meters per second.
