Problema Solution
Amy can run 100 meters in 13.4 seconds. Maya can run 100 meters in 7.2 seconds. How much of a headstart does Amy need to beat Maya?
Answer provided by our tutors
Amy's speed is:
v1 = 100/13.4
Mayas's speed is:
v2 = 100/7.2
Let t represents the headstart that Amy needs to beat Maya.
We will assume that they are rugning a distance of d = 100 m.
Since the difference in times is: 13.4 - 7.2 = 6.2 seconds
Amy will need not less than: 6.2*v1 = 6.2*(100/13.4) = 46.27 meters headstart.
