At 7 a.m., Japheth and Ben left Park G and drove towards Park H at average speeds of 74 km/h and 52 km/h respectively. Upon reaching Park H, Japheth rested for 3 hours. He then headed back for Park G at an average speed of 74 km/h along the same route. Japheth and Ben met each other on their way at 12 noon.
- How far had Japheth covered when he met Ben on the way?
- How far apart were the two parks?
(a)
Time taken by Ben = 5 h
Time taken by Japheth = 5 - 3 = 2 h
Distance covered by Japheth when he met Ben
= 2 x 74
= 148 km
(b)
Distance travelled by Ben
= 5 x 52
= 260 km
Distance of the two parks
= (148 + 260) ÷ 2
= 408 ÷ 2
= 204 km
Answer(s): (a) 148 km; (b) 204 km
