At 6 a.m., Luke and Albert left Park L and drove towards Park M at average speeds of 93 km/h and 60 km/h respectively. Upon reaching Park M, Luke rested for 2 hours. He then headed back for Park L at an average speed of 93 km/h along the same route. Luke and Albert met each other on their way at 12 noon.
- How far had Luke covered when he met Albert on the way?
- How far apart were the two parks?
(a)
Time taken by Albert = 6 h
Time taken by Luke = 6 - 2 = 4 h
Distance covered by Luke when he met Albert
= 4 x 93
= 372 km
(b)
Distance travelled by Albert
= 6 x 60
= 360 km
Distance of the two parks
= (372 + 360) ÷ 2
= 732 ÷ 2
= 366 km
Answer(s): (a) 372 km; (b) 366 km
