At 7 a.m., Jack and George left Park X and drove towards Park Y at average speeds of 84 km/h and 52 km/h respectively. Upon reaching Park Y, Jack rested for 2 hours. He then headed back for Park X at an average speed of 84 km/h along the same route. Jack and George met each other on their way at 12 noon.
- How far had Jack covered when he met George on the way?
- How far apart were the two parks?
(a)
Time taken by George = 5 h
Time taken by Jack = 5 - 2 = 3 h
Distance covered by Jack when he met George
= 3 x 84
= 252 km
(b)
Distance travelled by George
= 5 x 52
= 260 km
Distance of the two parks
= (252 + 260) ÷ 2
= 512 ÷ 2
= 256 km
Answer(s): (a) 252 km; (b) 256 km
