Rick is at Town A and Steve is at Town B. Both towns are connected by a road 110 k-
long. Rick starts driving at an average speed of 70 km/h from A towards B at 9,00 am
At 9,30 am, Steve starts driving from B towards 1 at an average speed of 80 kmh.
(a) How far has Rick travelled when Steve started on his journey?
(b) How far away from Town A will they meet?
30 minutes is 1/2 hr
70 km/ hr * 1/2 hr = 35 km
Together they are driving at a closing speed of 70 + 80 = 150 km/hr and they have 110 - 35 km before they meet
(110-35) km / 150 km/hr = 1/2 hr
so Rick will have travelled for an hour before they meet.....he will be 70 km from A when they meet.
