Question 804271: Two cars are racing around a circular track. The red car travels in a lane that is 82 ft from the center. The blue car is in a lane that is 90 ft from the center. If both cars travel at 120 mph, how much later, in seconds, will the blue car finish the race if they go one lap around the track? Round to the nearest 0.1 sec.

You can put this solution on YOUR website! Two cars are racing around a circular track. The red car travels in a lane that is 82 ft from the center.
The blue car is in a lane that is 90 ft from the center.
If both cars travel at 120 mph, how much later, in seconds, will the blue car finish the race if they go one lap around the track?
Round to the nearest 0.1
:
Find the circumference for each route = 565.5 ft = 515.2 ft
-------------------------
difference is: 50.3 ft
:
The blue car has to go 50.3 ft further than red car
Find how many seconds to go this distance at 120 mph = 176 ft/sec = .3 seconds later
