Answer:
Time taken to complete 100 revolutions will be 964 s
Step-by-step explanation:
Diameter of paddle wheel = 4 ft
So, circumference of wheel = C = π d
=> C = 4π
We know, the formula of speed s = d/t
where d is distance traveled and t is time taken.
We are given speed s= 1.3
Distance of wheel is equal to its circumference so, time taken will be:
s= d/t
=> t = d/s
=> t = 4π / 1.3
=> t = 3.07 * 3.14 s
=> t = 9.64 s
So, time taken to complete 100 revolutions will be:
9.64 * 100 = 964 s
Time taken to complete 100 revolutions will be 964 s
