At 5 a.m., Zane and Seth left Park R and drove towards Park S at average speeds of 86 km/h and 52 km/h respectively. Upon reaching Park S, Zane rested for 2 hours. He then headed back for Park R at an average speed of 86 km/h along the same route. Zane and Seth met each other on their way at 1 p.m.
- How far had Zane covered when he met Seth on the way?
- How far apart were the two parks?
(a)
Time taken by Seth = 8 h
Time taken by Zane = 8 - 2 = 6 h
Distance covered by Zane when he met Seth
= 6 x 86
= 516 km
(b)
Distance travelled by Seth
= 8 x 52
= 416 km
Distance of the two parks
= (516 + 416) ÷ 2
= 932 ÷ 2
= 466 km
Answer(s): (a) 516 km; (b) 466 km
