Calculating Time and Speed Differences

The video tutorial explains how to determine the time difference between two cars traveling at different speeds over the same distance. It uses the formula distance equals rate times time, rearranges it to solve for time, and calculates the time taken by each car to travel 100 miles. The times are converted from hours to minutes, and the difference is calculated and rounded to the nearest tenth of a minute.

What is the speed of the faster car in the problem?

• 55 miles per hour

• 60 miles per hour

• 65 miles per hour

• 70 miles per hour
