At 7 a.m., Pierre and Dylan left Park K and drove towards Park L at average speeds of 82 km/h and 55 km/h respectively. Upon reaching Park L, Pierre rested for 2 hours. He then headed back for Park K at an average speed of 82 km/h along the same route. Pierre and Dylan met each other on their way at 1 p.m.
- How far had Pierre covered when he met Dylan on the way?
- How far apart were the two parks?
(a)
Time taken by Dylan = 6 h
Time taken by Pierre = 6 - 2 = 4 h
Distance covered by Pierre when he met Dylan
= 4 x 82
= 328 km
(b)
Distance travelled by Dylan
= 6 x 55
= 330 km
Distance of the two parks
= (328 + 330) ÷ 2
= 658 ÷ 2
= 329 km
Answer(s): (a) 328 km; (b) 329 km
