Answer:
420 meters
Explanation:
Q. Benjamin is riding a unicycle. The tire of his unicycle has a circumference of 2.8 m, and the tire revolves 1.5 times per second. What is the distance Benjamin travels in 100 seconds?
Given:
Circumference of circular tire = 2.8 meters
Tire revolves per second = 1.5 times
Question asked:
What is the distance Benjamin travels in 100 seconds?
Solution:
Circumference of circular tire means distance covered by the unicycle's tire when it revolves 1 time that is 2.8 meters.
Now, by unitary method:
In 1 second, tire revolves = 1.5 times
In 100 seconds, tire revolves = 1.5 100
= 150 times
Distance covered by the tire when it revolves 1 time = 2.8 m
Distance covered by the tire when it revolves 150 times = 2.8 150
= 420 meters
Therefore, Benjamin travels 420 meters in 100 seconds.
