Question

A rowing team rowed an average of 14.4 miles per hour with the current and 6.8 miles per hour against the current. Determine the teams rowing speed in still water and the speed of the current.

Answer 1

Rowing speed: 10.6 miles per hour
speed of the current: 3.8 miles per hour.

Explanation:

Let the team's rowing speed in still water be "x" and the speed of the current be "c".

x + c = 14.4

x - c = 6.8

(x + c) + (x - c) = 14.4 + 6.8

2x = 21.2

x =
`(21.2)/(2)`

x = 10.6

10.6 + c = 14.4

c = 14.4 - 10.6

c = 3.8

The team's rowing speed in still water is 10.6 miles per hour, and the speed of the current is 3.8 miles per hour.
