At 6 a.m., Cole and David left Park M and drove towards Park N at average speeds of 96 km/h and 52 km/h respectively. Upon reaching Park N, Cole rested for 3 hours. He then headed back for Park M at an average speed of 96 km/h along the same route. Cole and David met each other on their way at 12 noon.
- How far had Cole covered when he met David on the way?
- How far apart were the two parks?
(a)
Time taken by David = 6 h
Time taken by Cole = 6 - 3 = 3 h
Distance covered by Cole when he met David
= 3 x 96
= 288 km
(b)
Distance travelled by David
= 6 x 52
= 312 km
Distance of the two parks
= (288 + 312) ÷ 2
= 600 ÷ 2
= 300 km
Answer(s): (a) 288 km; (b) 300 km
