The length of the subway is 113 miles. if 4.1 inches represents 677 miles, what is the length of the subway on the map? Round your answer to the nearest

hundredth if needed.

Answer 1

0.68 inches (nearest hundredth)

Explanation:

First, find the length on the map that represents 1 mile of the subway.

677 miles ----- 4.1 inches

1 mile ----- 4.1 ÷ 677= 0.0060561 inches (5 s.f.)

Multiply both sides by 113:

113 miles ----- 113(0.0060561)= 0.68 inches (nearest hundredth)

Thus, the length of the subway on the map is 0.68 inches.
