At 5 a.m., Zane and Michael left Park U and drove towards Park V at average speeds of 84 km/h and 54 km/h respectively. Upon reaching Park V, Zane rested for 3 hours. He then headed back for Park U at an average speed of 84 km/h along the same route. Zane and Michael met each other on their way at 12 noon.
- How far had Zane covered when he met Michael on the way?
- How far apart were the two parks?
(a)
Time taken by Michael = 7 h
Time taken by Zane = 7 - 3 = 4 h
Distance covered by Zane when he met Michael
= 4 x 84
= 336 km
(b)
Distance travelled by Michael
= 7 x 54
= 378 km
Distance of the two parks
= (336 + 378) ÷ 2
= 714 ÷ 2
= 357 km
Answer(s): (a) 336 km; (b) 357 km
