Using the formula Distance equals Speed multiplied by Time, the downstream speed of the boat is 24.5 kmph and the upstream speed is 15.5 kmph. If the boat travels entirely downstream, the distance covered is 24.5 multiplied by 2.5, which equals 61.25 km. If the boat travels entirely upstream, the distance covered is 15.5 multiplied by 2.5, which equals 38.75 km. Based on the options provided, the possible distance covered by the boat is 61.25 km.
