At 7 a.m., Neave and Oliver left Park A and drove towards Park B at average speeds of 76 km/h and 61 km/h respectively. Upon reaching Park B, Neave rested for 3 hours. He then headed back for Park A at an average speed of 76 km/h along the same route. Neave and Oliver met each other on their way at 1 p.m.
- How far had Neave covered when he met Oliver on the way?
- How far apart were the two parks?
(a)
Time taken by Oliver = 6 h
Time taken by Neave = 6 - 3 = 3 h
Distance covered by Neave when he met Oliver
= 3 x 76
= 228 km
(b)
Distance travelled by Oliver
= 6 x 61
= 366 km
Distance of the two parks
= (228 + 366) ÷ 2
= 594 ÷ 2
= 297 km
Answer(s): (a) 228 km; (b) 297 km
