At 6 a.m., Cody and Bobby left Park Y and drove towards Park Z at average speeds of 96 km/h and 60 km/h respectively. Upon reaching Park Z, Cody rested for 2 hours. He then headed back for Park Y at an average speed of 96 km/h along the same route. Cody and Bobby met each other on their way at 1 p.m.
- How far had Cody covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 7 h
Time taken by Cody = 7 - 2 = 5 h
Distance covered by Cody when he met Bobby
= 5 x 96
= 480 km
(b)
Distance travelled by Bobby
= 7 x 60
= 420 km
Distance of the two parks
= (480 + 420) ÷ 2
= 900 ÷ 2
= 450 km
Answer(s): (a) 480 km; (b) 450 km
