Car Battery Storage Capacity

Electrical problem of storage capacity.?

It takes an average of 45 horsepower to run an electric car at a speed average of 35 mph. Calculate the storage capacity of electricity from the battery system that would make this practical car for a trip 25 miles, recharge batteries only at home at night when electricity is cheap. How many D cell alkaline batteries would be needed for this? Explain in detail so that I can do on my own in the future.

1hp = 746 watts 33 570 watts 45 HP is we need to know the speed of the shuttle. Assuming that 35 mph is 25 mi/35 mph = 0.71 hours Is it a way of travel or return? assuming the latter, then it is 1.42 hours x 1.42 33 570 watt hours = 47,957 watt hour of energy for D cells have a capacity of 12 ampere-hour. x 1.5 volts, or 18 hours of energy per unit Watt. Watt 47,957 hours / 18 = 2664 cells watt-hr/cell ..
