At 5 a.m., Cole and Liam left Park D and drove towards Park E at average speeds of 78 km/h and 52 km/h respectively. Upon reaching Park E, Cole rested for 2 hours. He then headed back for Park D at an average speed of 78 km/h along the same route. Cole and Liam met each other on their way at 1 p.m.
- How far had Cole covered when he met Liam on the way?
- How far apart were the two parks?
(a)
Time taken by Liam = 8 h
Time taken by Cole = 8 - 2 = 6 h
Distance covered by Cole when he met Liam
= 6 x 78
= 468 km
(b)
Distance travelled by Liam
= 8 x 52
= 416 km
Distance of the two parks
= (468 + 416) ÷ 2
= 884 ÷ 2
= 442 km
Answer(s): (a) 468 km; (b) 442 km
