SSC CGL 20th August 2021 Shift-3

- Given:

- Distance upstream: 30 km in 3 hours.

- Distance downstream: 30 km in 1 hour.

- Calculate speeds:

- Upstream speed: 30 km / 3 hours = 10 km/h.

- Downstream speed: 30 km / 1 hour = 30 km/h.

- Find the speed of the boat in still water:

- Formula: (Downstream speed + Upstream speed) / 2.

- Calculation: (30 km/h + 10 km/h) / 2 = 20 km/h.

- Determine time to travel 60 km in still water:

- Formula: Distance / Speed.

- Calculation: 60 km / 20 km/h = 3 hours.

- Correct Option:

- Option 2: 3 hours.
