Question 986732
The truck had a 15 minutes head start and was going 60mph. That is a mile per minute. So 15 minutes later the car eters the road exactly 15 miles behind the truck.

The car is going 8mph faster than the truck. So how much time does it take to go 15 miles at 8 mph?

{{{distance = speed * time}}}
{{{15 = 8 * timeInHours}}}
{{{15/8 = timeInHours}}}
1.875 hours or 1:52 minutes 30 seconds
