Answer:
Washer = 300 [w-hr]
Dryer = 2200 [w-hr]
Explanation:
We have to calculate the power of each equipment during the respective time of use of each, in this way we will have:
Washer
400[w] * 45[min] * 1[hr/60min] = 300 [w-hr]
Dryer
2200[w] * 1 [hr] = 2200 [w-hr]
Note: We can see that the dryer machine is consuming more than 7 times the power of the washer machine in one hour.
