At 7 a.m., Warren and Perry left Park N and drove towards Park P at average speeds of 74 km/h and 64 km/h respectively. Upon reaching Park P, Warren rested for 2 hours. He then headed back for Park N at an average speed of 74 km/h along the same route. Warren and Perry met each other on their way at 12 noon.
- How far had Warren covered when he met Perry on the way?
- How far apart were the two parks?
(a)
Time taken by Perry = 5 h
Time taken by Warren = 5 - 2 = 3 h
Distance covered by Warren when he met Perry
= 3 x 74
= 222 km
(b)
Distance travelled by Perry
= 5 x 64
= 320 km
Distance of the two parks
= (222 + 320) ÷ 2
= 542 ÷ 2
= 271 km
Answer(s): (a) 222 km; (b) 271 km
