A hot air balloon travel two hours at a speed of 375 km/hours what distance did it travel

Distance = (speed) x (time)

Distance = (375 km/hr) x (2 hr)

Distance = 750 km

(That's about 233 miles per hour.  A hot-air balloon moving at that speed is in big serious trouble.  I hope there's nobody trapped in the basket.)

Explanation:

This happens because the gas inside tend to expand because its temperature gets higher.

This is why the balloon that is put in a freezer for too long tend to gets smaller, because the gas temperature that is inside the balloon decreases.

(you can try it at home)

It is related to the temperature of the gas.
