Problem Analysis

To solve this problem, we can use the formula: time = distance / (boat_speed + river_speed) for the downstream journey, and time = distance / (boat_speed - river_speed) for the upstream journey.

Given: - Downstream distance = 100 km - Downstream river speed = 1 km/h - Upstream distance = 99.47 km - Upstream river speed = 1 km/h - Boat speed = 36.4 km/h

Downstream Journey

Using the formula time = distance / (boat_speed + river_speed): - Time for downstream journey = 100 / (36.4 + 1) = 2.7027 hours

Upstream Journey

Using the formula time = distance / (boat_speed - river_speed): - Time for upstream journey = 99.47 / (36.4 - 1) = 2.8571 hours

Total Time

The total time spent by the boat for the entire journey is the sum of the downstream and upstream times: - Total time = 2.7027 + 2.8571 = 5.5598 hours

Therefore, the boat spent approximately 5.56 hours for the entire journey.
