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 cardiovascular 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.
