At 6 a.m., Julian and Ken left Park N and drove towards Park P at average speeds of 91 km/h and 53 km/h respectively. Upon reaching Park P, Julian rested for 2 hours. He then headed back for Park N at an average speed of 91 km/h along the same route. Julian and Ken met each other on their way at 12 noon.
- How far had Julian covered when he met Ken on the way?
- How far apart were the two parks?
(a)
Time taken by Ken = 6 h
Time taken by Julian = 6 - 2 = 4 h
Distance covered by Julian when he met Ken
= 4 x 91
= 364 km
(b)
Distance travelled by Ken
= 6 x 53
= 318 km
Distance of the two parks
= (364 + 318) ÷ 2
= 682 ÷ 2
= 341 km
Answer(s): (a) 364 km; (b) 341 km
