Practice Question Rohan started from home to school at 9 a.m. on bicycle. His brother started for office at 10:15 a.m. on scooter in the same direction and caught up with him at 12:30 p.m. If Rohan’s speed is 12 km/h, then what is his brother’s speed?
First, calculate the time Rohan and his brother traveled. Since they met at 12:30 p.m., you can find the time each of them spent traveling. Then, use the formula: Speed = Distance / Time to calculate Rohan’s brother’s speed.
