Answer:
3 mph
Step-by-step explanation:
Let c represent the current of the river in miles per hour. Then the ratio of speed downstream to speed upstream is ...
(21 +c)/(21 -c) = 2.4/1.8
1.8(21 +c) = 2.4(21 -c) . . . . . . multiply by 1.8(21-c)
37.8 + 1.8c = 50.4 -2.4c . . . . eliminate parentheses
4.2c = 12.6 . . . . . . . . . . . . . . . add 2.4c-37.8
c = 3 . . . . . . . . . . . . . . . . . . . .divide by 4.2
The current of the river is 3 miles per hour.
