Question

On the map it is 7.5 inches from Chicago to Cincinnati. Traveling at 65 mi/h, how long will it take to drive from Chicago to Cincinnati? Round to the nearest tenth of an hour.

Answer 1

1 inch = 40 miles...so 7.5 inches = (7.5 * 40) = 300 miles
time = distance / speed
t = 300 / 65
t = 4.6 hrs <==

Answer 2

If one inch is 40 miles then the distance is  40*7.5  or 300 miles. driving 300 miles at 65 mph would take you 4.62 hours. 4.62 hours is equal to 4 hours and 37 minutes
