At 5 a.m., Cody and Asher left Park H and drove towards Park J at average speeds of 99 km/h and 65 km/h respectively. Upon reaching Park J, Cody rested for 2 hours. He then headed back for Park H at an average speed of 99 km/h along the same route. Cody and Asher met each other on their way at 2 p.m.
- How far had Cody covered when he met Asher on the way?
- How far apart were the two parks?
(a)
Time taken by Asher = 9 h
Time taken by Cody = 9 - 2 = 7 h
Distance covered by Cody when he met Asher
= 7 x 99
= 693 km
(b)
Distance travelled by Asher
= 9 x 65
= 585 km
Distance of the two parks
= (693 + 585) ÷ 2
= 1278 ÷ 2
= 639 km
Answer(s): (a) 693 km; (b) 639 km
