At 8 a.m., Jack and Warren left Park V and drove towards Park W at average speeds of 70 km/h and 64 km/h respectively. Upon reaching Park W, Jack rested for 2 hours. He then headed back for Park V at an average speed of 70 km/h along the same route. Jack and Warren met each other on their way at 2 p.m.
- How far had Jack covered when he met Warren on the way?
- How far apart were the two parks?
(a)
Time taken by Warren = 6 h
Time taken by Jack = 6 - 2 = 4 h
Distance covered by Jack when he met Warren
= 4 x 70
= 280 km
(b)
Distance travelled by Warren
= 6 x 64
= 384 km
Distance of the two parks
= (280 + 384) ÷ 2
= 664 ÷ 2
= 332 km
Answer(s): (a) 280 km; (b) 332 km
