Rumi leaves her home at 1:30pm and drives at 40km/hour.at 2pm buzo starts from the same place and moves at an average speed of 50km/hour. When will buzo catch up with rumi |

Answer» Answer: 4pm at 50kmph SPEED EXPLANATION: For Buzo to catch up with Rumi, his speed should be GREATER than Rumi ( this is not provided in question statement). Taking Buzo’s speed at 50 kmph Distance covered by Rumi 1:30 PM to 2 pm = ½ hr x 40 km/hr = 20 kms. Now relative speed of Rumi and Buzo would be; =(50−40) = 10 km/hr Required time by Buzo = 20 km10 km/hr = 2 hours Therefore Buzo TRAVELLING at 50km/h would catch up with Rumi at 4 pm |
