At 7 a.m., Charlie and Valen left Park M and drove towards Park N at average speeds of 87 km/h and 57 km/h respectively. Upon reaching Park N, Charlie rested for 2 hours. He then headed back for Park M at an average speed of 87 km/h along the same route. Charlie and Valen met each other on their way at 12 noon.
- How far had Charlie covered when he met Valen on the way?
- How far apart were the two parks?
(a)
Time taken by Valen = 5 h
Time taken by Charlie = 5 - 2 = 3 h
Distance covered by Charlie when he met Valen
= 3 x 87
= 261 km
(b)
Distance travelled by Valen
= 5 x 57
= 285 km
Distance of the two parks
= (261 + 285) ÷ 2
= 546 ÷ 2
= 273 km
Answer(s): (a) 261 km; (b) 273 km
