At 5 a.m., Carl and Seth left Park V and drove towards Park W at average speeds of 96 km/h and 60 km/h respectively. Upon reaching Park W, Carl rested for 3 hours. He then headed back for Park V at an average speed of 96 km/h along the same route. Carl and Seth met each other on their way at 12 noon.
- How far had Carl covered when he met Seth on the way?
- How far apart were the two parks?
(a)
Time taken by Seth = 7 h
Time taken by Carl = 7 - 3 = 4 h
Distance covered by Carl when he met Seth
= 4 x 96
= 384 km
(b)
Distance travelled by Seth
= 7 x 60
= 420 km
Distance of the two parks
= (384 + 420) ÷ 2
= 804 ÷ 2
= 402 km
Answer(s): (a) 384 km; (b) 402 km
