Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet
Pretty sure it’s A sorry if that’s wrong
Distance = 3 units .....................
It will take 90 minutes.
Why?
Rene has to go 60 miles.
He takes 1 hour to go 40 miles.
60 miles is 'one and a half' times 40.
So, he needs an hour and a half to go 60 miles.
