At 5 a.m., Zeph and Harry left Park Y and drove towards Park Z at average speeds of 76 km/h and 56 km/h respectively. Upon reaching Park Z, Zeph rested for 3 hours. He then headed back for Park Y at an average speed of 76 km/h along the same route. Zeph and Harry met each other on their way at 12 noon.
- How far had Zeph covered when he met Harry on the way?
- How far apart were the two parks?
(a)
Time taken by Harry = 7 h
Time taken by Zeph = 7 - 3 = 4 h
Distance covered by Zeph when he met Harry
= 4 x 76
= 304 km
(b)
Distance travelled by Harry
= 7 x 56
= 392 km
Distance of the two parks
= (304 + 392) ÷ 2
= 696 ÷ 2
= 348 km
Answer(s): (a) 304 km; (b) 348 km
