Van Speed -> 48km/h
Car speed -> 60km/h
Since they are driving towards each other. Find out the distance they would have travelled such that both will add up to 216km
After 2 hours:
Van would have travelled 96km
Car would have travelled 120km
96km + 120km = 216km
So we know they met 2 hours later
a) 2 hours after 11:50am is 1:50pm
b) van travelled 96km
