Asteamer going downstream traveled the distance between two ports in 3 hours. the return trip took 3 hours 40 minutes. find the speed of the water current if the speed of the steamer in still water is 18 mph.

1.8 mph

Step-by-step explanation:

If the water's speed is v, and the distance between the ports is d, then:

d = (18 + v) (3)

d = (18 − v) (3⅔)

Set the distances equal:

(18 + v) (3) = (18 − v) (3⅔)

54 + 3v = 66 − 3⅔ v

6⅔ v = 12

v = 1.8

The speed of the water is 1.8 mph.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%

the answer would be 44.79
