Question

Callie's grandmother pledged R150, 00 for every mile Callie walked in her walk-a-thon. Callie walked 14.5 km. How much does her grandmother owe? ( assume 8 km = 5miles)

Answer 1

Given:-

Callie walked 14.5 km. And also given 8 km=5 miles.

At first we convert 14.5 km to miles. we get,

`\begin{gathered} 14.5*(5)/(8)=(72.5)/(8) \\ \text{ =9.0625} \end{gathered}`

So 14.5 km is 9.0625 miles.

Callie's grandmother pledged Rs. 150 for every mile. so for 9.0625 miles it is,

`9.0625*150=1359.375`

So her grandmother owe Rs. 1359.375
