At 6 a.m., Zane and Bobby left Park Y and drove towards Park Z at average speeds of 96 km/h and 63 km/h respectively. Upon reaching Park Z, Zane rested for 3 hours. He then headed back for Park Y at an average speed of 96 km/h along the same route. Zane and Bobby met each other on their way at 12 noon.
- How far had Zane covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 6 h
Time taken by Zane = 6 - 3 = 3 h
Distance covered by Zane when he met Bobby
= 3 x 96
= 288 km
(b)
Distance travelled by Bobby
= 6 x 63
= 378 km
Distance of the two parks
= (288 + 378) ÷ 2
= 666 ÷ 2
= 333 km
Answer(s): (a) 288 km; (b) 333 km
