Best answer
Correct Answer - Option 1 : 5 & 1 km/h

Given:

A boat takes 8h to row 48 km downstream and 12h to row the same distance upstream

Calculation:

⇒ The speed of downstream of the boat = 48/8 = 6 km/h

⇒ The speed of upstream of the boat = 48/12 = 4 km/h

⇒ The speed of the boat = (6 + 4)/2 = 5 km/h

⇒ The speed of current = (6 - 4)/2 = 1 km/h

∴ The required result will be "5 & 1" km/h.
