At 7 a.m., Ken and Tim left Park V and drove towards Park W at average speeds of 80 km/h and 64 km/h respectively. Upon reaching Park W, Ken rested for 3 hours. He then headed back for Park V at an average speed of 80 km/h along the same route. Ken and Tim met each other on their way at 12 noon.
- How far had Ken covered when he met Tim on the way?
- How far apart were the two parks?
(a)
Time taken by Tim = 5 h
Time taken by Ken = 5 - 3 = 2 h
Distance covered by Ken when he met Tim
= 2 x 80
= 160 km
(b)
Distance travelled by Tim
= 5 x 64
= 320 km
Distance of the two parks
= (160 + 320) ÷ 2
= 480 ÷ 2
= 240 km
Answer(s): (a) 160 km; (b) 240 km
