At 6 a.m., Simon and Julian left Park Y and drove towards Park Z at average speeds of 86 km/h and 59 km/h respectively. Upon reaching Park Z, Simon rested for 3 hours. He then headed back for Park Y at an average speed of 86 km/h along the same route. Simon and Julian met each other on their way at 12 noon.
- How far had Simon covered when he met Julian on the way?
- How far apart were the two parks?
(a)
Time taken by Julian = 6 h
Time taken by Simon = 6 - 3 = 3 h
Distance covered by Simon when he met Julian
= 3 x 86
= 258 km
(b)
Distance travelled by Julian
= 6 x 59
= 354 km
Distance of the two parks
= (258 + 354) ÷ 2
= 612 ÷ 2
= 306 km
Answer(s): (a) 258 km; (b) 306 km
