## 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.
