The main source of a hurricane's energy comes from heat water wind land

The actual answer is heat.

latent heat of water

Explanation: the hurricane pulls more strength to it self by drawing surface air towards it's low pressure center

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
