Car X began traveling at an average speed of 35 miles per hour. After 72 minutes, car Y began traveling at an average speed of 49 miles per hour. When both cars had traveled the same distance, both cars stopped. How many miles did car X travel from the time car Y began traveling until both cars stopped?
Choose the correct choice from the following options
A) 105	B) 120	C) 140	D) 147	E) 168
Car Y began travelling after 72 minutes or 1.2 hours.   Let t be the time for which car Y travelled before it stopped.   Both cars stop when they have travelled the same distance.   So,   35(t+1.2) = 49t   or 5t+6=7t   or t=3   Distance travelled by car X from the time car Y began traveling until both cars stopped is   35 x 3   = 105 miles   105nswer:- 105
