At 6 a.m., Caden and Lee left Park A and drove towards Park B at average speeds of 78 km/h and 54 km/h respectively. Upon reaching Park B, Caden rested for 3 hours. He then headed back for Park A at an average speed of 78 km/h along the same route. Caden and Lee met each other on their way at 12 noon.
- How far had Caden covered when he met Lee on the way?
- How far apart were the two parks?
(a)
Time taken by Lee = 6 h
Time taken by Caden = 6 - 3 = 3 h
Distance covered by Caden when he met Lee
= 3 x 78
= 234 km
(b)
Distance travelled by Lee
= 6 x 54
= 324 km
Distance of the two parks
= (234 + 324) ÷ 2
= 558 ÷ 2
= 279 km
Answer(s): (a) 234 km; (b) 279 km
