At 7 a.m., Cole and Zane left Park K and drove towards Park L at average speeds of 83 km/h and 62 km/h respectively. Upon reaching Park L, Cole rested for 3 hours. He then headed back for Park K at an average speed of 83 km/h along the same route. Cole and Zane met each other on their way at 12 noon.
- How far had Cole covered when he met Zane on the way?
- How far apart were the two parks?
(a)
Time taken by Zane = 5 h
Time taken by Cole = 5 - 3 = 2 h
Distance covered by Cole when he met Zane
= 2 x 83
= 166 km
(b)
Distance travelled by Zane
= 5 x 62
= 310 km
Distance of the two parks
= (166 + 310) ÷ 2
= 476 ÷ 2
= 238 km
Answer(s): (a) 166 km; (b) 238 km
