Question 1064008: Joe is trying to soup up his dragster. He knows that the time needed for the car to go from 0 to 100 miles per hour varies inversely with the car's horsepower. At 200 horsepower, the car can go from 0 to 100 mph in 12 seconds. How long should the car take if he can increase the horsepower to 240 hp?

Time+%28alpha%29%281%2FP%29

Time+=k%2A%281%2FP%29
p=200, t=12 s
12= k*1/200
k=2400
Now
P=240, t=?
t= 2400*(1/240)
t= 10s
The car should take 10 seconds to go from 0 to 100 mph at 240 hp
