At 6 a.m., Zeph and Howard left Park G and drove towards Park H at average speeds of 80 km/h and 59 km/h respectively. Upon reaching Park H, Zeph rested for 3 hours. He then headed back for Park G at an average speed of 80 km/h along the same route. Zeph and Howard met each other on their way at 12 noon.
- How far had Zeph covered when he met Howard on the way?
- How far apart were the two parks?
(a)
Time taken by Howard = 6 h
Time taken by Zeph = 6 - 3 = 3 h
Distance covered by Zeph when he met Howard
= 3 x 80
= 240 km
(b)
Distance travelled by Howard
= 6 x 59
= 354 km
Distance of the two parks
= (240 + 354) ÷ 2
= 594 ÷ 2
= 297 km
Answer(s): (a) 240 km; (b) 297 km
