Question

John took a 5 and 1/2 mile walk to his friends house left at 11 a.M. And arrived at his friends house at 1 p.M. What was his average speed of walking speed is measured in miles per hour into your answer as a mixed number a space between the whole number and fraction

Answer 1

Answer:
`1\frac56\text{ miles per hour.}`

Explanation:

Given: Total distance traveled =
`5\frac12\text{ miles}`

`=(2*5+1)/(2)\text{ miles}\\\\=(11)/(2)\text{ miles}`

They started at 11 A.M at cam back at 1 PM , that means it took 3 hours to cover
`\frac{11}2` miles.

Now,
`speed=(distance)/(time)`

`\Rightarrow\ speed =\frac{\frac{11}2}{3}=(11)/(6)\\\\=(6*1+5)/(6)\\\\=1\frac56\text{ miles per hour.}`

Hence, the average speed of walking speed =
`1\frac56\text{ miles per hour.}`
