Question 510665
The receiver in a football game catches a pass 45 yards from the end zone.
 He runs 12 yards per second toward the end zone.
 The defender is 10 yards behind the receiver.
 He runs 14 yards per second toward the end zone.
 If not, by how much time will the receiver beat him?:
:
Find the time it takes the receiver to cover 45 yds (time = dist/speed)
{{{45/12}}} = 3.75 sec
Find the time it takes the defender to cover 55 yds
{{{55/14}}} ~ 3.9 sec
:
Receiver will reach the goal line: 3.9 - 3.75 = .15 sec before the defender
