Answer:
13 km/h for 65 km
9 km/h for the next 27 km
Explanation:
Velocity of canoe =x km/h for 65 km
Velocity of canoe =x-4 km/h for 27 km after covering 65 km
Total time taken = 9 hours
So,
Solving this quadratic equation we get,
Speed cannot be 2.5 as the speed will become negative for the 27 km stretch.
So, velocity of canoe is <u>13 km/h</u> for 65 km and <u>9 km/h</u> for the next 27 km
