At 7 a.m., Neave and Archie left Park V and drove towards Park W at average speeds of 86 km/h and 52 km/h respectively. Upon reaching Park W, Neave rested for 3 hours. He then headed back for Park V at an average speed of 86 km/h along the same route. Neave and Archie met each other on their way at 12 noon.
- How far had Neave covered when he met Archie on the way?
- How far apart were the two parks?
(a)
Time taken by Archie = 5 h
Time taken by Neave = 5 - 3 = 2 h
Distance covered by Neave when he met Archie
= 2 x 86
= 172 km
(b)
Distance travelled by Archie
= 5 x 52
= 260 km
Distance of the two parks
= (172 + 260) ÷ 2
= 432 ÷ 2
= 216 km
Answer(s): (a) 172 km; (b) 216 km
