Let the distance to be travelled be ‘x’ km Time taken when speed is 11 km/hr = (x/11) hours Time taken when speed is 22 km/hr = (x/22) hours According to the question, (x/11) – (x/22) = 2 Or, 2x – x = 2 × 22 Or, x = 44 km Time taken to travel 44 km with speed of 11 km/hr = 44/11 = 4 hours Therefore, he started at 12 – 4 = 8 a.m. Therefore, required speed to reach the destination at 11 a.m. or 4 hours = 44/3 = 14.66 km/hr
