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.
