Answer:

55.75 mi/hr


Step-by-step explanation:

Formula for average speed is:

Average Speed = [tex]\frac{TotalDistance}{TotalTime}[/tex]


Total distance is 203 + 243 = 446 miles

Total time taken is 3.5 + 4.5 = 8 hours

Average Speed = [tex]\frac{446}{8}=55.75mph[/tex]


First option is correct.

Answer:

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

Step-by-step 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

[tex]v=\frac{446}{8}[/tex]

[tex]v=55.75mi/h[/tex]
