At 7 a.m., Oliver and Liam left Park V and drove towards Park W at average speeds of 78 km/h and 64 km/h respectively. Upon reaching Park W, Oliver rested for 2 hours. He then headed back for Park V at an average speed of 78 km/h along the same route. Oliver and Liam met each other on their way at 12 noon.
- How far had Oliver covered when he met Liam on the way?
- How far apart were the two parks?
(a)
Time taken by Liam = 5 h
Time taken by Oliver = 5 - 2 = 3 h
Distance covered by Oliver when he met Liam
= 3 x 78
= 234 km
(b)
Distance travelled by Liam
= 5 x 64
= 320 km
Distance of the two parks
= (234 + 320) ÷ 2
= 554 ÷ 2
= 277 km
Answer(s): (a) 234 km; (b) 277 km
