At 7 a.m., Neave and Lee left Park K and drove towards Park L at average speeds of 91 km/h and 58 km/h respectively. Upon reaching Park L, Neave rested for 2 hours. He then headed back for Park K at an average speed of 91 km/h along the same route. Neave and Lee met each other on their way at 1 p.m.
- How far had Neave covered when he met Lee on the way?
- How far apart were the two parks?
(a)
Time taken by Lee = 6 h
Time taken by Neave = 6 - 2 = 4 h
Distance covered by Neave when he met Lee
= 4 x 91
= 364 km
(b)
Distance travelled by Lee
= 6 x 58
= 348 km
Distance of the two parks
= (364 + 348) ÷ 2
= 712 ÷ 2
= 356 km
Answer(s): (a) 364 km; (b) 356 km
