Question

What is the value of time, t, for the given values of distance, d, and rate, r?

d = 425 m, r = 50 m/s

A.
8.5 m

B.
8.5 s

C.
21,250 m

D.
21,250 s

Answer 1

The value of time is 8.5 seconds. Choice B.

Distance = Rate x Time
Time = Distance / Rate
Rate = Distance / Time

Given: 
Distance = 425m
Rate = 50 m/s
Time = ?

Time = Distance / Rate
Time = 425m ÷ 50 m/s
Time = 8.5 s
