At 8 a.m., Zeph and Mark left Park V and drove towards Park W at average speeds of 84 km/h and 58 km/h respectively. Upon reaching Park W, Zeph rested for 2 hours. He then headed back for Park V at an average speed of 84 km/h along the same route. Zeph and Mark met each other on their way at 2 p.m.
- How far had Zeph covered when he met Mark on the way?
- How far apart were the two parks?
(a)
Time taken by Mark = 6 h
Time taken by Zeph = 6 - 2 = 4 h
Distance covered by Zeph when he met Mark
= 4 x 84
= 336 km
(b)
Distance travelled by Mark
= 6 x 58
= 348 km
Distance of the two parks
= (336 + 348) ÷ 2
= 684 ÷ 2
= 342 km
Answer(s): (a) 336 km; (b) 342 km
