At 6 a.m., Japheth and Gabriel left Park W and drove towards Park X at average speeds of 76 km/h and 62 km/h respectively. Upon reaching Park X, Japheth rested for 3 hours. He then headed back for Park W at an average speed of 76 km/h along the same route. Japheth and Gabriel met each other on their way at 12 noon.
- How far had Japheth covered when he met Gabriel on the way?
- How far apart were the two parks?
(a)
Time taken by Gabriel = 6 h
Time taken by Japheth = 6 - 3 = 3 h
Distance covered by Japheth when he met Gabriel
= 3 x 76
= 228 km
(b)
Distance travelled by Gabriel
= 6 x 62
= 372 km
Distance of the two parks
= (228 + 372) ÷ 2
= 600 ÷ 2
= 300 km
Answer(s): (a) 228 km; (b) 300 km
