Please provide thorough answer explaining and showing work so i can learn the concept as well

Answer 1

Given: Ray has a stride of about 1.4 m. He runs 9 km daily to train.

Required: To determine the no of strides Ray takes to run 9 km.

Explanation: The length of 1 stride is 1.4 m, and the total length is 9 km. So we need to divide the total length by the length of one stride to get the no of strides.

Let Ray takes x no of strides to run 9 km. Then we have-

`x*1.4\text{ m}=9\text{ km}`

We need to convert the unit to the same units. In 9 km, we have 9000 m.

Hence,

`\begin{gathered} x=(9000)/(1.4) \\ x=6428.57 \end{gathered}`

Final Answer: Ray needs approximately 6429 steps.
