A motorcycle has a magnet attached to the rim of its front wheel. The front tire has a diameter of 60cm . A magnetic pickup is attached to the front forks and receives an electronic
Pulse each time the magnet passes by. How far has the motorcycle traveled when the pickup has
Received 10 pulses?
A) 600cm
B) 600 ft
C) 1885cm
D) 1.885m

Question

Quizplus · Accepted Answer

The circumference of the front wheel can be found by using the formula:

Circumference = π x diameter

C = π x 60cm 
C ≈ 188.5cm

Each time the magnet passes by, the pickup receives one pulse, and the motorcycle would have traveled a distance equal to its circumference.

So, for 10 pulses received:

Distance traveled = 10 x Circumference 
Distance traveled = 10 x 188.5cm 
Distance traveled = 1885cm

Thus, the answer is C, 1885cm.
