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-
[tex]x\times1.4\text{ m}=9\text{ km}[/tex]
We need to convert the unit to the same units. In 9 km, we have 9000 m.
Hence,
[tex]\begin{gathered} x=\frac{9000}{1.4} \\ x=6428.57 \end{gathered}[/tex]
Final Answer: Ray needs approximately 6429 steps.
