At 7 a.m., Oliver and Zeph left Park Y and drove towards Park Z at average speeds of 76 km/h and 62 km/h respectively. Upon reaching Park Z, Oliver rested for 2 hours. He then headed back for Park Y at an average speed of 76 km/h along the same route. Oliver and Zeph met each other on their way at 12 noon.
- How far had Oliver covered when he met Zeph on the way?
- How far apart were the two parks?
(a)
Time taken by Zeph = 5 h
Time taken by Oliver = 5 - 2 = 3 h
Distance covered by Oliver when he met Zeph
= 3 x 76
= 228 km
(b)
Distance travelled by Zeph
= 5 x 62
= 310 km
Distance of the two parks
= (228 + 310) ÷ 2
= 538 ÷ 2
= 269 km
Answer(s): (a) 228 km; (b) 269 km
