At 7 a.m., Oscar and Harry left Park A and drove towards Park B at average speeds of 100 km/h and 52 km/h respectively. Upon reaching Park B, Oscar rested for 2 hours. He then headed back for Park A at an average speed of 100 km/h along the same route. Oscar and Harry met each other on their way at 12 noon.
- How far had Oscar covered when he met Harry on the way?
- How far apart were the two parks?
(a)
Time taken by Harry = 5 h
Time taken by Oscar = 5 - 2 = 3 h
Distance covered by Oscar when he met Harry
= 3 x 100
= 300 km
(b)
Distance travelled by Harry
= 5 x 52
= 260 km
Distance of the two parks
= (300 + 260) ÷ 2
= 560 ÷ 2
= 280 km
Answer(s): (a) 300 km; (b) 280 km
