At 8 a.m., Brandon and Tommy left Park Q and drove towards Park R at average speeds of 90 km/h and 55 km/h respectively. Upon reaching Park R, Brandon rested for 2 hours. He then headed back for Park Q at an average speed of 90 km/h along the same route. Brandon and Tommy met each other on their way at 2 p.m.
- How far had Brandon covered when he met Tommy on the way?
- How far apart were the two parks?
(a)
Time taken by Tommy = 6 h
Time taken by Brandon = 6 - 2 = 4 h
Distance covered by Brandon when he met Tommy
= 4 x 90
= 360 km
(b)
Distance travelled by Tommy
= 6 x 55
= 330 km
Distance of the two parks
= (360 + 330) ÷ 2
= 690 ÷ 2
= 345 km
Answer(s): (a) 360 km; (b) 345 km
