At 6 a.m., Zane and Asher left Park J and drove towards Park K at average speeds of 90 km/h and 60 km/h respectively. Upon reaching Park K, Zane rested for 3 hours. He then headed back for Park J at an average speed of 90 km/h along the same route. Zane and Asher met each other on their way at 12 noon.
- How far had Zane covered when he met Asher on the way?
- How far apart were the two parks?
(a)
Time taken by Asher = 6 h
Time taken by Zane = 6 - 3 = 3 h
Distance covered by Zane when he met Asher
= 3 x 90
= 270 km
(b)
Distance travelled by Asher
= 6 x 60
= 360 km
Distance of the two parks
= (270 + 360) ÷ 2
= 630 ÷ 2
= 315 km
Answer(s): (a) 270 km; (b) 315 km
