Question 990757: Little Red Riding Hood, in order to make it to Grandma's house and back home in time for her piano lesson needs to average 4mph for the 8-mile trip (4 miles each way). If Little Red Riding Hood goes 2 mph on the way to her Grandma's house, how fast does she need to go on the way back to make it home in time?
Answer by macston(5194)   (Show Source):
You can put this solution on YOUR website! She can't make it. To average 4mph,
she would have to make the 8 mile trip in 2 hours.
At 2 mph, she spent the entire 2 hours on the way
to Grandma's, so she cannot make it home in time.
