Suppose your 1460kg sports car has a 250hp engine that's 40% efficient. (That is, 40% of the 250hp can be converted into the car's motion.) Find the car's maximum speed after accelerating from rest for 3.3s
I think you need to calculate the acceleration given the power available and the weight of the car. I think the acceleration can then be substituted into the usual equations.
