At 5 a.m., Dylan and Liam left Park Z and drove towards Park A at average speeds of 80 km/h and 58 km/h respectively. Upon reaching Park A, Dylan rested for 2 hours. He then headed back for Park Z at an average speed of 80 km/h along the same route. Dylan and Liam met each other on their way at 12 noon.
- How far had Dylan covered when he met Liam on the way?
- How far apart were the two parks?
(a)
Time taken by Liam = 7 h
Time taken by Dylan = 7 - 2 = 5 h
Distance covered by Dylan when he met Liam
= 5 x 80
= 400 km
(b)
Distance travelled by Liam
= 7 x 58
= 406 km
Distance of the two parks
= (400 + 406) ÷ 2
= 806 ÷ 2
= 403 km
Answer(s): (a) 400 km; (b) 403 km
