At 6 a.m., Lee and George left Park L and drove towards Park M at average speeds of 76 km/h and 61 km/h respectively. Upon reaching Park M, Lee rested for 3 hours. He then headed back for Park L at an average speed of 76 km/h along the same route. Lee and George met each other on their way at 12 noon.
- How far had Lee covered when he met George on the way?
- How far apart were the two parks?
(a)
Time taken by George = 6 h
Time taken by Lee = 6 - 3 = 3 h
Distance covered by Lee when he met George
= 3 x 76
= 228 km
(b)
Distance travelled by George
= 6 x 61
= 366 km
Distance of the two parks
= (228 + 366) ÷ 2
= 594 ÷ 2
= 297 km
Answer(s): (a) 228 km; (b) 297 km
