Distance, Speed, and Time Calculations

The video tutorial explains how to calculate the distance a car traveling 15 mph faster than another car will be ahead after 5 minutes. It uses the formula D = RT, where D is distance, R is rate, and T is time. The tutorial covers converting time from minutes to hours and then calculating the distance in miles. Finally, it converts the distance from miles to feet, resulting in the car being 6,600 feet ahead after 5 minutes.

What is the initial speed difference between the two cars?

• 10 miles per hour

• 15 miles per hour

• 20 miles per hour

• 25 miles per hour
