please.. this is due by midnight and i’m close to tears.. from a point in a straight road, Chris and Elena ride bicycles in the same direction. Chris rides at 10mph and Elena rides at 14 mph. In how many hours will they be at 34 mi apart?
Chris is going 10 mph. After 9 hours, Chris has gone 90 miles. Elena is going 14 mph. After 9 hours, she has gone 126 miles. 126 miles is 36 miles more then 90 miles.
