Two men, A and B, start toward each other at the same time from points 510 miles apart. If they travel 40 and 4 milea an hour respectively, in how many hours will they meet.
RELATIVE SPEED WHILE TRAVELLING IN OPPOSITE DIRECTION TO EACH OTHER = S1+S2=40+4=44 MPH.
INTIAL DISTANCE OF SEPERATION =510 MILES.
FINAL DISTANCE OF SEPERATION =0
HENCE DISTANCE TO BE COVERED TOGETHER = 510 -0 =510 MILES
TIME NEEDED =DISTANCE / RELATIVE SPEED = 510/44 HRS
