Question

Robert enters a race. The race is 10 kilometers long, but he is more familiar with miles than kilometers. How many miles are in 10 kilometers to the nearest tenth of a mile?

Answer 1

The distance to be covered in the race is 10 kilometers. However we need to convert this to miles.

Note that, the standard rate of conversion is;

$1\operatorname{km}=0.621371\text{miles}$

Therefore, to convert 10 km to miles, we shall take the following steps;

$\begin{gathered} 1\operatorname{km}=0.621371\text{miles} \\ 10\operatorname{km}=0.621371\times10\text{ miles} \\ 10km=6.21371miles \\ \text{Rounded to the nearest tenth of a mile;} \\ 10\operatorname{km}=6.2\text{miles} \end{gathered}$

ANSWER:

The distance in miles is 6.2 miles (rounded to the nearest tenth)
