Question

Mr ismail and Madam Chan left their office at 17:15 and drove separately to their colleague's home for a festive dinner. Mr Ismail and Madam Chan drove at a constant speed of 63km/h and 57 hm/h respectively. Mr Ismail reached the colleague's home at 17:35. How far away was Madam Chan from the colleague's home when Mr Ismail reached?

Answer 1

Answer = 2km

Solution:

35-15=20 min ---> the time of the vehicle.

20/60 = 1/3 (h)

63-57= 6 (KM/H) ---> the speed difference between the 2 cars.

6x 1/3 = 2km

So the answer is 2km.
