Answer:

D . 58 miles

Step-by-step explanation:

In order to find the distance travelled (d) in each stage, we will use the following expression.

d = v × t

where,

v: speed

t: time

First stage

v = 70 mi/h

t = 45 min × (1 h / 60 min) = 0.75 h

d = v × t = 70 mi/h × 0.75 h = 53 mi

Second stage

v = 20 mi/h

t = 15 min × (1 h / 60 min) = 0.25 h

d = v × t = 20 mi/h × 0.25 h = 5.0 mi

The total distance tyraveled is 53 mi + 5.0 mi = 58 mi
