712 hours

Explanation:

Vacuum cleaner uses 58=1016 kilowatt per hour

Clothes dryer uses 41116=7516 kilowatt per hour

To see how many hours we can run the vacuum cleaner for using the same amount of energy as the dryer does for one hour, we can divide the vacuum cleaner energy into the dryer energy:

75161016=7516×1610=7510=7.5

Jonas can run his vacuum for 712 hours using the same amount of energy that the dryer does in one hour.
