A chevy is traveling at 15 miles per hour and is 200 yards ahead.
A ford is traveling at 20 miles per hour. How far will the Chevy travel before the ford catches up?
:
Use the relative speed here 20 - 15 = 5 mph is the relative speed
:
How long will it take to cover 200 yds at 5 mph is the question
:
Convert 5 mph to yards/sec (1760 yds in a mile, 3600 sec in 1 hr)
%285%2A1760%29%2F3600 = 2.44 yds/sec
How long to cover 200 yds at this speed
t = 200%2F2.44
t = 82 seconds to cover the 200 yds
:
How far will the Chevy travel before the ford catches up?
%2815%2A1760%29%2F3600 * 82 = 601.33 yds
