The speed of water in a whirlpool varies inversely with the radius. if water speed is 2.5 feet per second at a radius of 30 feet what is the speed of the watte at a radius of 3 feet?

The speed of the watte at a radius of 3 feet is 25 ft per sec.

Step-by-step explanation:

Let s represents the speed of water and r represents the radius,

Since, the speed of water in a whirlpool varies inversely with the radius,

Where, k is the constant of proportionality,

Given,

When, s = 2.5 ft per sec then, r = 30 ft,

So, from equation (1),

Again from equation (1),

The equation that shows the relation between r and s is,

If r = 3 ft,

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

70.30
