At 6 a.m., Ryan and Neave left Park K and drove towards Park L at average speeds of 86 km/h and 57 km/h respectively. Upon reaching Park L, Ryan rested for 3 hours. He then headed back for Park K at an average speed of 86 km/h along the same route. Ryan and Neave met each other on their way at 12 noon.
- How far had Ryan covered when he met Neave on the way?
- How far apart were the two parks?
(a)
Time taken by Neave = 6 h
Time taken by Ryan = 6 - 3 = 3 h
Distance covered by Ryan when he met Neave
= 3 x 86
= 258 km
(b)
Distance travelled by Neave
= 6 x 57
= 342 km
Distance of the two parks
= (258 + 342) ÷ 2
= 600 ÷ 2
= 300 km
Answer(s): (a) 258 km; (b) 300 km
