Hendrik's average running speed is 375 m/min. This is 25 m/min faster than Esteban's running speed. If they want to finish at the same time, how much of a head-start, in time, should Esteban get for a 1500 m run
:
E's speed = 350 m/min
:
Let x = head-start time
:
Write a time equation: (Time = dist/speed)
:
H's time + head-start time = E's time
+ x =
:
4 + x = 4.3
x = 4.3 - 4
x = .3 min head start (.3 * 60 = 18 sec)
