At 6 a.m., Japheth and Zeph left Park N and drove towards Park P at average speeds of 95 km/h and 64 km/h respectively. Upon reaching Park P, Japheth rested for 2 hours. He then headed back for Park N at an average speed of 95 km/h along the same route. Japheth and Zeph met each other on their way at 12 noon.
- How far had Japheth covered when he met Zeph on the way?
- How far apart were the two parks?
(a)
Time taken by Zeph = 6 h
Time taken by Japheth = 6 - 2 = 4 h
Distance covered by Japheth when he met Zeph
= 4 x 95
= 380 km
(b)
Distance travelled by Zeph
= 6 x 64
= 384 km
Distance of the two parks
= (380 + 384) ÷ 2
= 764 ÷ 2
= 382 km
Answer(s): (a) 380 km; (b) 382 km
