**Anonymous**, Saturday, August 10, 2013 at 3:10pmFirst, multiply 450 by 2, which is 900 calories for one hour. Now, for the 3/4, set up a proportion.

.50 / 450 = .75 / ?

450 X .75 = 337.5

337.5 / .50 = 675.

So, Jennifer will burn 675 calories every 3/4 of an hour.

900 + 675 = 1575, the number of calories Jennifer will burn if she rides her bike for 1 3/4 hours.
