Let the distance to be travelled be ‘x’ km Time taken when speed is 24 km/hr = (x/24) hours Time taken when speed is 48 km/hr = (x/48) hours According to the question, (x/24) – (x/48) = 2 Or, 2x – x = 2 × 48 Or, x = 96 km Time taken to travel 96 km with speed of 24 km/hr = 96/24 = 4 hours Therefore, he started at 12 – 4 = 8 a.m. Therefore, required speed to reach the destination at 11 a.m. or 3 hours = 96/3 = 32 km/hr
