At 6 a.m., Luis and Warren left Park S and drove towards Park T at average speeds of 90 km/h and 62 km/h respectively. Upon reaching Park T, Luis rested for 3 hours. He then headed back for Park S at an average speed of 90 km/h along the same route. Luis and Warren met each other on their way at 12 noon.
- How far had Luis covered when he met Warren on the way?
- How far apart were the two parks?
(a)
Time taken by Warren = 6 h
Time taken by Luis = 6 - 3 = 3 h
Distance covered by Luis when he met Warren
= 3 x 90
= 270 km
(b)
Distance travelled by Warren
= 6 x 62
= 372 km
Distance of the two parks
= (270 + 372) ÷ 2
= 642 ÷ 2
= 321 km
Answer(s): (a) 270 km; (b) 321 km
