Question 374445: Two cars are racing around a circular track. The red car is traveling 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 are traveling at 120 mph, how much later, in seconds, will the blue car finish if they race one lap around the track. (round to the nearest 0.1 sec)(HINT: 60 mph= 88fps) Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Two cars are racing around a circular track.
The red car is traveling 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 are traveling at 120 mph, how much later, in seconds, will
the blue car finish if they race one lap around the track.
(round to the nearest 0.1 sec)(HINT: 60 mph= 88fps)
:
We know that 120 mph = 176 ft/sec
:
Find the circumference of each, divide by speed
:
dif = -
dif = .285599 ~ .3 sec
