Question

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 1

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
