At 8 a.m., Ken and Luis left Park V and drove towards Park W at average speeds of 99 km/h and 52 km/h respectively. Upon reaching Park W, Ken rested for 3 hours. He then headed back for Park V at an average speed of 99 km/h along the same route. Ken and Luis met each other on their way at 1 p.m.
- How far had Ken covered when he met Luis on the way?
- How far apart were the two parks?
(a)
Time taken by Luis = 5 h
Time taken by Ken = 5 - 3 = 2 h
Distance covered by Ken when he met Luis
= 2 x 99
= 198 km
(b)
Distance travelled by Luis
= 5 x 52
= 260 km
Distance of the two parks
= (198 + 260) ÷ 2
= 458 ÷ 2
= 229 km
Answer(s): (a) 198 km; (b) 229 km
