At 7 a.m., Pierre and Cole left Park N and drove towards Park P at average speeds of 89 km/h and 61 km/h respectively. Upon reaching Park P, Pierre rested for 2 hours. He then headed back for Park N at an average speed of 89 km/h along the same route. Pierre and Cole met each other on their way at 12 noon.
- How far had Pierre covered when he met Cole on the way?
- How far apart were the two parks?
(a)
Time taken by Cole = 5 h
Time taken by Pierre = 5 - 2 = 3 h
Distance covered by Pierre when he met Cole
= 3 x 89
= 267 km
(b)
Distance travelled by Cole
= 5 x 61
= 305 km
Distance of the two parks
= (267 + 305) ÷ 2
= 572 ÷ 2
= 286 km
Answer(s): (a) 267 km; (b) 286 km
