At 7 a.m., Zeph and Nick left Park U and drove towards Park V at average speeds of 74 km/h and 57 km/h respectively. Upon reaching Park V, Zeph rested for 3 hours. He then headed back for Park U at an average speed of 74 km/h along the same route. Zeph and Nick met each other on their way at 1 p.m.
- How far had Zeph covered when he met Nick on the way?
- How far apart were the two parks?
(a)
Time taken by Nick = 6 h
Time taken by Zeph = 6 - 3 = 3 h
Distance covered by Zeph when he met Nick
= 3 x 74
= 222 km
(b)
Distance travelled by Nick
= 6 x 57
= 342 km
Distance of the two parks
= (222 + 342) ÷ 2
= 564 ÷ 2
= 282 km
Answer(s): (a) 222 km; (b) 282 km
