Question

An electric car can travel at top speed for 107 km on 5 h charging time. If the car died after just traveling 65 km at top speed, how long a charge could it have held?

A.) 4h B.) 2.5h C.) 3h D.) 3.5h

Answer 1

9514 1404 393

Answer:

C.) 3 h

Explanation:

If you assume the distance is proportional to the charge time, then ...

x/5 = 65/107

x = 5(65/107) ≈ 3.04

The car may have held about a 3-hour charge.
