Question 335000: What is an equation for the following word problem?
Lois rode her bike to visit a friend. She traveled at 10 mi/h. While she was there, it began to rain. Her friend drove her home in a car traveling at 25 mi/h. Lois took 1.5 h longer to go to her friend's than to return home. How many hours did it take Lois to ride to her friend's house? Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! Let the distance = x miles
Speed = 10mph
Time taken = Distance / speed = x/10 hours
Returning time taken = x/25
x/10 - x/25 = 1.5
MULTIPLY BY 50 both sides
5x - 2x = 75
3x = 75
x = 25 miles
Time taken = 25/10 = 2.5 hours ANSWER
