At 9 a.m., Cody and Carl left Park N and drove towards Park P at average speeds of 70 km/h and 61 km/h respectively. Upon reaching Park P, Cody rested for 2 hours. He then headed back for Park N at an average speed of 70 km/h along the same route. Cody and Carl met each other on their way at 1 p.m.
- How far had Cody covered when he met Carl on the way?
- How far apart were the two parks?
(a)
Time taken by Carl = 4 h
Time taken by Cody = 4 - 2 = 2 h
Distance covered by Cody when he met Carl
= 2 x 70
= 140 km
(b)
Distance travelled by Carl
= 4 x 61
= 244 km
Distance of the two parks
= (140 + 244) ÷ 2
= 384 ÷ 2
= 192 km
Answer(s): (a) 140 km; (b) 192 km
