At 5 a.m., Zane and Pierre left Park M and drove towards Park N at average speeds of 89 km/h and 58 km/h respectively. Upon reaching Park N, Zane rested for 3 hours. He then headed back for Park M at an average speed of 89 km/h along the same route. Zane and Pierre met each other on their way at 12 noon.
- How far had Zane covered when he met Pierre on the way?
- How far apart were the two parks?
(a)
Time taken by Pierre = 7 h
Time taken by Zane = 7 - 3 = 4 h
Distance covered by Zane when he met Pierre
= 4 x 89
= 356 km
(b)
Distance travelled by Pierre
= 7 x 58
= 406 km
Distance of the two parks
= (356 + 406) ÷ 2
= 762 ÷ 2
= 381 km
Answer(s): (a) 356 km; (b) 381 km
