At 8 a.m., Liam and Paul left Park A and drove towards Park B at average speeds of 96 km/h and 56 km/h respectively. Upon reaching Park B, Liam rested for 2 hours. He then headed back for Park A at an average speed of 96 km/h along the same route. Liam and Paul met each other on their way at 1 p.m.
- How far had Liam covered when he met Paul on the way?
- How far apart were the two parks?
(a)
Time taken by Paul = 5 h
Time taken by Liam = 5 - 2 = 3 h
Distance covered by Liam when he met Paul
= 3 x 96
= 288 km
(b)
Distance travelled by Paul
= 5 x 56
= 280 km
Distance of the two parks
= (288 + 280) ÷ 2
= 568 ÷ 2
= 284 km
Answer(s): (a) 288 km; (b) 284 km
