A paddle wheel on a boat is 4 feet in diameter. The fins along the outer edge travel at a speed of 1.3 feet per second. How long does it take the paddle wheel to complete 100 full revolutions? Round to the nearest second.

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
