At 9 a.m., Bryan and Justin left Park R and drove towards Park S at average speeds of 88 km/h and 62 km/h respectively. Upon reaching Park S, Bryan rested for 2 hours. He then headed back for Park R at an average speed of 88 km/h along the same route. Bryan and Justin met each other on their way at 2 p.m.
- How far had Bryan covered when he met Justin on the way?
- How far apart were the two parks?
(a)
Time taken by Justin = 5 h
Time taken by Bryan = 5 - 2 = 3 h
Distance covered by Bryan when he met Justin
= 3 x 88
= 264 km
(b)
Distance travelled by Justin
= 5 x 62
= 310 km
Distance of the two parks
= (264 + 310) ÷ 2
= 574 ÷ 2
= 287 km
Answer(s): (a) 264 km; (b) 287 km
