At 5 a.m., Dylan and Albert left Park R and drove towards Park S at average speeds of 88 km/h and 64 km/h respectively. Upon reaching Park S, Dylan rested for 2 hours. He then headed back for Park R at an average speed of 88 km/h along the same route. Dylan and Albert met each other on their way at 12 noon.
- How far had Dylan covered when he met Albert on the way?
- How far apart were the two parks?
(a)
Time taken by Albert = 7 h
Time taken by Dylan = 7 - 2 = 5 h
Distance covered by Dylan when he met Albert
= 5 x 88
= 440 km
(b)
Distance travelled by Albert
= 7 x 64
= 448 km
Distance of the two parks
= (440 + 448) ÷ 2
= 888 ÷ 2
= 444 km
Answer(s): (a) 440 km; (b) 444 km
