At 6 a.m., Luis and Howard left Park K and drove towards Park L at average speeds of 70 km/h and 53 km/h respectively. Upon reaching Park L, Luis rested for 3 hours. He then headed back for Park K at an average speed of 70 km/h along the same route. Luis and Howard met each other on their way at 12 noon.
- How far had Luis covered when he met Howard on the way?
- How far apart were the two parks?
(a)
Time taken by Howard = 6 h
Time taken by Luis = 6 - 3 = 3 h
Distance covered by Luis when he met Howard
= 3 x 70
= 210 km
(b)
Distance travelled by Howard
= 6 x 53
= 318 km
Distance of the two parks
= (210 + 318) ÷ 2
= 528 ÷ 2
= 264 km
Answer(s): (a) 210 km; (b) 264 km
