Question

A delivery truck drove 203 miles in 3.5 hours. After unloading and loading new cargo, it traveled on another 243 miles for 4.5 hours. What was the average speed of the truck over its entire route? Round to the nearest hundredth, if necessary. 55.75 mi/h 56.00 mi/h 58.00 mi/h 63.70 mi/h

Answer 1

The average speed of the truck over its entire range is 55.75 mi/h

Explanation:

We are given

A delivery truck drove 203 miles in 3.5 hours.

After unloading and loading new cargo, it traveled on another 243 miles for 4.5 hours

Total distance =203+243=246 miles

Total time =3.5+4.5=8 hours

we know that

speed = distance/ time

we can plug values

and we get

`v=(446)/(8)`

`v=55.75mi/h`

Answer 2

55.75 mi/hr

Explanation:

Formula for average speed is:

Average Speed =
`(TotalDistance)/(TotalTime)`

Total distance is 203 + 243 = 446 miles

Total time taken is 3.5 + 4.5 = 8 hours

Average Speed =
`(446)/(8)=55.75mph`

First option is correct.
