The kinetic energy will be 687.186 BTU
Explanation:
We have given mass of car = 2500 lbm
We know that 1 lbm = 0.4535 kg
So 2500 lbm = 
Speed = 80 mph
We know that 1 mile = 1609.34 meter
1 hour = 3600 sec
So 
We know that kinetic energy 
We know that 1 KJ = 0.9478 BTU
So 725.033 KJ = 725.033×0.9478 = 687.186 BTU
