Answer:
The linear speed of the vehicle is approximately 0.798 miles per hour.
Explanation:
The circumference of a tire is given by the formula C = πd, where d is the diameter of the tire. So, the circumference of each tire is:
C = πd = π(32 inches) ≈ 100.53 inches
Now, to find the distance that the vehicle travels in one revolution of each tire, we use the circumference formula again:
distance traveled in one revolution = circumference of the tire = 100.53 inches
Since the tires are rotating at a rate of 800 revolutions per minute, the vehicle travels a distance of:
distance traveled in one minute = distance traveled in one revolution × number of revolutions per minute
= 100.53 inches/revolution × 800 revolutions/minute
= 80424 inches/minute
To convert this to miles per hour, we need to divide by the number of inches per mile and the number of minutes per hour:
speed = (80424 inches/minute) × (1 mile/63360 inches) × (60 minutes/1 hour)
≈ 0.798 miles/hour
Therefore, the linear speed of the vehicle is approximately 0.798 miles per hour.
