At 6 a.m., Julian and Zane left Park Y and drove towards Park Z at average speeds of 86 km/h and 60 km/h respectively. Upon reaching Park Z, Julian rested for 3 hours. He then headed back for Park Y at an average speed of 86 km/h along the same route. Julian and Zane met each other on their way at 1 p.m.
- How far had Julian covered when he met Zane on the way?
- How far apart were the two parks?
(a)
Time taken by Zane = 7 h
Time taken by Julian = 7 - 3 = 4 h
Distance covered by Julian when he met Zane
= 4 x 86
= 344 km
(b)
Distance travelled by Zane
= 7 x 60
= 420 km
Distance of the two parks
= (344 + 420) ÷ 2
= 764 ÷ 2
= 382 km
Answer(s): (a) 344 km; (b) 382 km
