Answer: 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= [tex]45 \times63360[/tex]
i.e. speed=2851200 inches/hr
Now since the revolutions are asked in one minute
So speed= [tex]\frac{2851200}{60}[/tex]
=47520 inches/min
Now In one revolution distance travelled by wheel=2πr or πd
=[tex]3.14\times 48[/tex]
=150.72 inches
No of revolutions =Total distance travelled/Distance travelled in one revolution
=[tex]\frac{47520}{150.72}[/tex]
=315.28 revolutions
