Question

an electric car battery, when fully charged, can travel 490 miles. the car uses 412 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

Remaining miles = Total miles - Used miles. So, \(490 - 412=78\) miles.

Step2: Calculate the percentage

The formula for percentage is \(\frac{\text{Part}}{\text{Whole}}\times100\). Here, the part is the remaining miles (\(78\)) and the whole is the total miles (\(490\)). So, \(\frac{78}{490}\times 100=\frac{7800}{490}\approx 15.92\)

Answer:

\(15.92\)
