Question

an electric car battery, when fully charged, can travel 410 miles. the car uses 192 miles of charge on a drive. enter the percentage (rounded to the nearest hundredth) of miles the car has left in battery charge.

Explanation:

Step1: Calculate remaining miles

The car can travel 410 miles when fully - charged and has used 192 miles of charge. So the remaining miles of charge is $410 - 192=218$ miles.

Step2: Calculate the percentage

The percentage of remaining charge is $\frac{218}{410}\times100$.
\[

$$\begin{align*} \frac{218}{410}\times100&=\frac{21800}{410}\\ &\approx53.17 \end{align*}$$

\]

Answer:

53.17
