Question

Natasha spent 1 1/2 hours on the beach. She fell asleep for 3/4 of the time she was on the beach and then woke up with a terrible sunburn.
How many hours was Natasha asleep on the beach?

Answer 1

Answer:

Hours spent on the beach= 3/2 hrs

Hours she was asleep =  3/4 of 3/2 hrs= 3/4 x 3/2 = 9/8 hrs = 9/8 = 1 1/8 hr

= 1 hour and 7.5 minutes.
