At 5 a.m., Cody and Albert left Park G and drove towards Park H at average speeds of 84 km/h and 64 km/h respectively. Upon reaching Park H, Cody rested for 2 hours. He then headed back for Park G at an average speed of 84 km/h along the same route. Cody and Albert met each other on their way at 2 p.m.
- How far had Cody covered when he met Albert on the way?
- How far apart were the two parks?
(a)
Time taken by Albert = 9 h
Time taken by Cody = 9 - 2 = 7 h
Distance covered by Cody when he met Albert
= 7 x 84
= 588 km
(b)
Distance travelled by Albert
= 9 x 64
= 576 km
Distance of the two parks
= (588 + 576) ÷ 2
= 1164 ÷ 2
= 582 km
Answer(s): (a) 588 km; (b) 582 km
