At 7 a.m., Ryan and Peter left Park G and drove towards Park H at average speeds of 81 km/h and 53 km/h respectively. Upon reaching Park H, Ryan rested for 2 hours. He then headed back for Park G at an average speed of 81 km/h along the same route. Ryan and Peter met each other on their way at 12 noon.
- How far had Ryan covered when he met Peter on the way?
- How far apart were the two parks?
(a)
Time taken by Peter = 5 h
Time taken by Ryan = 5 - 2 = 3 h
Distance covered by Ryan when he met Peter
= 3 x 81
= 243 km
(b)
Distance travelled by Peter
= 5 x 53
= 265 km
Distance of the two parks
= (243 + 265) ÷ 2
= 508 ÷ 2
= 254 km
Answer(s): (a) 243 km; (b) 254 km
