At 6 a.m., Vincent and Japheth left Park A and drove towards Park B at average speeds of 96 km/h and 60 km/h respectively. Upon reaching Park B, Vincent rested for 2 hours. He then headed back for Park A at an average speed of 96 km/h along the same route. Vincent and Japheth met each other on their way at 12 noon.
- How far had Vincent covered when he met Japheth on the way?
- How far apart were the two parks?
(a)
Time taken by Japheth = 6 h
Time taken by Vincent = 6 - 2 = 4 h
Distance covered by Vincent when he met Japheth
= 4 x 96
= 384 km
(b)
Distance travelled by Japheth
= 6 x 60
= 360 km
Distance of the two parks
= (384 + 360) ÷ 2
= 744 ÷ 2
= 372 km
Answer(s): (a) 384 km; (b) 372 km
