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?

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.
