Walking a mile at a slow pace, from 1.8 to 2.5 mph

Question

Walking a mile at a slow pace, from 1.8 to 2.5 mph, burns about 100 calories. Walking a mile at a brisk pace, from 3 to 4 mph, also burns about 100 calories, though in a shorter amount of time. Jogging a mile, from 4.5 to 6 mph, burns about the same 100 calories. The difference in covering a mile at faster speeds is not in the number of calories burned, but in the greater degree of cardio-vascular benefit.

Which of the following conclusions is best supported by the statements above?

A)Jogging builds more muscle tone than does walking at a slow pace.

B)Speed is directly proportional to the number of calories burned.

C)Walking at a brisk pace for a shorter amount of time burns more calories than does walking at a slow pace for a longer amount of time.

D)There are benefits to walking at a slow pace other than burning calories.

E)Jogging a mile offers greater cardiovascular benefit than does walking a mile briskly or at a slow pace.
