Dave can now mow his lawn in 20 minutes less time with the power moxer than with his hand mower. One day the power mower broke down 15 minutes after he started mowing, and he took 25 minutes more time to complete the job with the hand mower. How many minutes does dave take to mow the lawn with the power mower?
