At 6 a.m., Lee and Michael left Park Y and drove towards Park Z at average speeds of 97 km/h and 53 km/h respectively. Upon reaching Park Z, Lee rested for 2 hours. He then headed back for Park Y at an average speed of 97 km/h along the same route. Lee and Michael met each other on their way at 12 noon.
- How far had Lee covered when he met Michael on the way?
- How far apart were the two parks?
(a)
Time taken by Michael = 6 h
Time taken by Lee = 6 - 2 = 4 h
Distance covered by Lee when he met Michael
= 4 x 97
= 388 km
(b)
Distance travelled by Michael
= 6 x 53
= 318 km
Distance of the two parks
= (388 + 318) ÷ 2
= 706 ÷ 2
= 353 km
Answer(s): (a) 388 km; (b) 353 km
