Homework Statement



A car needs 40 hp to move continuously at 60 mph. How long would 1 kg of hydrogen (talking about hydrogen fuel cells) move such a car, hence how many miles at 60 mph, if 1 kg of hydrogen provides 16 kWh of motive energy?

Homework Equations



1 hp = 746 W
1 kW = 1000 W

The Attempt at a Solution



40 hp = 29.8 kW and we have 16 kWh of power
I don't know where to factor in the 60 mph, though.

The sixty mph is only needed to compute the distance traveled from using the fuel cell. You first need to compute how long it would last.
