Answer:
C. 67 mph
Step-by-step explanation:
The speedometer reports speed based on the number of revolutions the tire makes in a given time period. If the motorcycle travels 28/25 times as far on each revolution, its speed is 28/25 times as great.
(28/25)(60 mph) = 67.2 mph ≈ 67 mph
_____
The distance traveled is proportional to the circumference of the tire, which is proportional to the diameter. Hence, actual speed for a given speedometer reading is proportional to the diameter of the tire.
