At 5 a.m., Zeph and Neave left Park M and drove towards Park N at average speeds of 97 km/h and 65 km/h respectively. Upon reaching Park N, Zeph rested for 2 hours. He then headed back for Park M at an average speed of 97 km/h along the same route. Zeph and Neave met each other on their way at 12 noon.
- How far had Zeph covered when he met Neave on the way?
- How far apart were the two parks?
(a)
Time taken by Neave = 7 h
Time taken by Zeph = 7 - 2 = 5 h
Distance covered by Zeph when he met Neave
= 5 x 97
= 485 km
(b)
Distance travelled by Neave
= 7 x 65
= 455 km
Distance of the two parks
= (485 + 455) ÷ 2
= 940 ÷ 2
= 470 km
Answer(s): (a) 485 km; (b) 470 km
