Question 1165448: Marck rode his bike for 2 hours at a constant rate. During the first 1.5 hours, he rode 21 miles. How many miles did Jesse ride his bike during the last half hour? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 21 mi/1.5 hr=14 mi/hr.
In two hours, he went 14 mi/hr*2 hr or 28 miles,
7 miles in the past half hour, assuming there is a typo and Marck was still riding the bike, not Jesse.
