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

v=\frac{446}{8}

v=55.75mi/h

Answer:

55.75 mi/hr


Step-by-step explanation:

Formula for average speed is:

Average Speed = \frac{TotalDistance}{TotalTime}


Total distance is 203 + 243 = 446 miles

Total time taken is 3.5 + 4.5 = 8 hours

Average Speed = \frac{446}{8}=55.75mph


First option is correct.

As much as possible, the sum of the length of the two remaining side must be greater than the other side. Given the side is 30, then the sum of the two remaining sides should be greater than 30 inches.
