Step-by-step explanation:

8 mph

Step-by-step explanation:

Let's say x is the speed of the current, and t is the time.  When travelling with the current, the boat's speed is 54 + x.  When travelling against the current, the boat's speed is 54 – x.

Distance = rate × time

124 = (54 + x) t

92 = (54 – x) t

Solve for t in each equation:

t = 124 / (54 + x)

t = 92 / (54 – x)

Set equal:

124 / (54 + x) = 92 / (54 – x)

Cross multiply:

124 (54 – x) = 92 (54 + x)

Distribute and solve:

6696 – 124x = 4968 + 92x

1728 = 216x

x = 8

The speed of the current is 8 mph.
