At 9 a.m., Oscar and Simon left Park X and drove towards Park Y at average speeds of 72 km/h and 54 km/h respectively. Upon reaching Park Y, Oscar rested for 2 hours. He then headed back for Park X at an average speed of 72 km/h along the same route. Oscar and Simon met each other on their way at 1 p.m.
- How far had Oscar covered when he met Simon on the way?
- How far apart were the two parks?
(a)
Time taken by Simon = 4 h
Time taken by Oscar = 4 - 2 = 2 h
Distance covered by Oscar when he met Simon
= 2 x 72
= 144 km
(b)
Distance travelled by Simon
= 4 x 54
= 216 km
Distance of the two parks
= (144 + 216) ÷ 2
= 360 ÷ 2
= 180 km
Answer(s): (a) 144 km; (b) 180 km
