At 9 a.m., Julian and Cody left Park C and drove towards Park D at average speeds of 93 km/h and 64 km/h respectively. Upon reaching Park D, Julian rested for 2 hours. He then headed back for Park C at an average speed of 93 km/h along the same route. Julian and Cody met each other on their way at 1 p.m.
- How far had Julian covered when he met Cody on the way?
- How far apart were the two parks?
(a)
Time taken by Cody = 4 h
Time taken by Julian = 4 - 2 = 2 h
Distance covered by Julian when he met Cody
= 2 x 93
= 186 km
(b)
Distance travelled by Cody
= 4 x 64
= 256 km
Distance of the two parks
= (186 + 256) ÷ 2
= 442 ÷ 2
= 221 km
Answer(s): (a) 186 km; (b) 221 km
