At 6 a.m., Neave and Elijah left Park C and drove towards Park D at average speeds of 80 km/h and 65 km/h respectively. Upon reaching Park D, Neave rested for 3 hours. He then headed back for Park C at an average speed of 80 km/h along the same route. Neave and Elijah met each other on their way at 12 noon.
- How far had Neave covered when he met Elijah on the way?
- How far apart were the two parks?
(a)
Time taken by Elijah = 6 h
Time taken by Neave = 6 - 3 = 3 h
Distance covered by Neave when he met Elijah
= 3 x 80
= 240 km
(b)
Distance travelled by Elijah
= 6 x 65
= 390 km
Distance of the two parks
= (240 + 390) ÷ 2
= 630 ÷ 2
= 315 km
Answer(s): (a) 240 km; (b) 315 km
