Marcus is working on his dragster.
He knows that the time needed for the car to go from 0 to 100 miles per hour varies inversely with the cars horsepower,
the car can go from 0 to 100mph in 10seconds.
How long should the car take to go from 0 to 100 if he can increase the horsepower to 250hp?:
:
If it is linear, (and I am not sure that it really is)
What is the original horsepower? Assume that it is 200 hp
let t = time for go from 0 to 100 with 250 hp
=
cross multiply
250t = 10*200
t =
t = 8 seconds when increase to 250 hp from 200 hp
