At 8 a.m., Japheth and Oliver left Park Y and drove towards Park Z at average speeds of 95 km/h and 51 km/h respectively. Upon reaching Park Z, Japheth rested for 2 hours. He then headed back for Park Y at an average speed of 95 km/h along the same route. Japheth and Oliver met each other on their way at 2 p.m.
- How far had Japheth covered when he met Oliver on the way?
- How far apart were the two parks?
(a)
Time taken by Oliver = 6 h
Time taken by Japheth = 6 - 2 = 4 h
Distance covered by Japheth when he met Oliver
= 4 x 95
= 380 km
(b)
Distance travelled by Oliver
= 6 x 51
= 306 km
Distance of the two parks
= (380 + 306) ÷ 2
= 686 ÷ 2
= 343 km
Answer(s): (a) 380 km; (b) 343 km
