What is the speed of a car traveling east 85 miles over 45 minutes ? 0.5 mph 1.9 miles per minute
1.9 miles per minute East
0.52 mph

1.9 miles per minute

Explanation:

The speed of a substance can be calculated by using the formula:

S = d/t

Where;

S = speed (m/s)

D = distance (m)

t = time (s)

In this question, the units for the distance and time are miles and minutes respectively. Hence, the speed is:

S = 85miles ÷ 45 mins

S = 1.888 miles/min

S = 1.9 miles per minute
