At 7 a.m., Vincent and Julian left Park C and drove towards Park D at average speeds of 91 km/h and 64 km/h respectively. Upon reaching Park D, Vincent rested for 3 hours. He then headed back for Park C at an average speed of 91 km/h along the same route. Vincent and Julian met each other on their way at 12 noon.
- How far had Vincent covered when he met Julian on the way?
- How far apart were the two parks?
(a)
Time taken by Julian = 5 h
Time taken by Vincent = 5 - 3 = 2 h
Distance covered by Vincent when he met Julian
= 2 x 91
= 182 km
(b)
Distance travelled by Julian
= 5 x 64
= 320 km
Distance of the two parks
= (182 + 320) ÷ 2
= 502 ÷ 2
= 251 km
Answer(s): (a) 182 km; (b) 251 km
