Answer:

Step-by-step explanation:
Given

First, we need to list the multiples of 5

Then, multiples of 3
Next, is to list out the common elements in both


The required probability is then calculated as thus:



R = speed in still water
r + c = speed with current
r - c = speed against current
3.5(r + c) = 70
r + c = 20
c = 20 - r
4(r + c) = distance from pier to pier
5(r - c) = distance from pier to pier
4(r + c) = 5(r - c)
4(r + 20 - r) = 5(r - 20 + r)
80 = 10r - 100
180 = 10r
18 = r
The speed in still water is 18 km/hour
