Question:

Benjamin is riding a unicycle. The tire of his unicycle has a circumference of 2.8 m, and the tire revolves 1.5 per second. What is the distance Benjamin travels in 100 seconds?

Answer:

186.87 m

Step-by-step explanation:

1.5 seconds = 2.8 m

1 second = 2.8 ÷ 1.5 = 28/15 m

100 seconds = 28/15 x 100 = 186.67 m

Answer: It travels 186.67 m in 100 seconds

Answer 2

Answer:

420 m

Step-by-step explanation:

Given:

Circumference of unicycle = 2.8 m

Tire revolves 1.5 times in 1 second

To Find:

Distance covered in 100 seconds

Solution:

Distance covered in 1 second = 2.8 * 1.5

                                                 =4.2 m

Distance covered in 100 seconds = 4.2 * 100

                                                        = 420 m
