Aconvertible is traveling at 45 miles per hour, and its wheels have a diameter of 48 inches. how many complete revolutions do the wheels make in one minute?

The wheel make 315 complete revolutions in one minute

Step-by-step explanation: Given speed of convertible =45 miles/hr

Firstly we will convert miles to inches

We know that 1 mile= 63360 inches

So 45 miles=

i.e. speed=2851200 inches/hr

Now since the revolutions are asked in one minute

So speed=

=47520 inches/min

Now In one revolution distance travelled by wheel=2πr or πd

=

=150.72 inches

No of revolutions =Total distance travelled/Distance travelled in one revolution

=

=315.28 revolutions

b. 13

step-by-step explanation:

as there are 13 students in bowling class therefore the most reasonable answer is b as only 13 students are in the bowling class.
