Question

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 47 minutes? In 1 hour?

Answer 1

• Distance in 47 minutes = 0.75 × 47 = 35.25 miles

• Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles

Explanation:

Given that the car is traveling at a steady speed.

Distance traveled in 2 1/3 or 7/3 or (2.33) minutes = 1 3/4 miles

= 7/4 or 1.75 miles

Thus,

distance in 1 minute: 1.75/2.33 = 0.75 miles per minute

Thus,

• Distance in 47 minutes = 0.75 × 47 = 35.25 miles

• Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
