Question

Max is already 224 miles into his road trip. If he is averaging 52 miles per hour and the trip is 640 miles total, how many more hours does he have left to drive?

Answer 1

8 hours.

Explanation:

We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.

Let us find the remaining distance of trip by subtracting the distance already covered from total distance.

`\text{Remaining distance}=640\text{ miles}-224\text{ miles}`

`\text{Remaining distance}=416\text{ miles}`

We will use formula:
`\text{Time}=\frac{\text{Distance}}{\text{Speed}}` to find the number of hours Max still have to drive.

`\text{Time}=\frac{416\text{ miles}}{52\frac{\text{ miles}}{\text{hour}}}`

`\text{Time}=\frac{416\text{ miles}}{52}* \frac{\text{hour}}{\text{ miles}}`

`\text{Time}=(416)/(52)\text{ hour}`

`\text{Time}=8\text{ hour}`

Therefore, Max have left 8 more hours to drive.
