At 7 a.m., Luis and Rael left Park B and drove towards Park C at average speeds of 90 km/h and 50 km/h respectively. Upon reaching Park C, Luis rested for 2 hours. He then headed back for Park B at an average speed of 90 km/h along the same route. Luis and Rael met each other on their way at 12 noon.
- How far had Luis covered when he met Rael on the way?
- How far apart were the two parks?
(a)
Time taken by Rael = 5 h
Time taken by Luis = 5 - 2 = 3 h
Distance covered by Luis when he met Rael
= 3 x 90
= 270 km
(b)
Distance travelled by Rael
= 5 x 50
= 250 km
Distance of the two parks
= (270 + 250) ÷ 2
= 520 ÷ 2
= 260 km
Answer(s): (a) 270 km; (b) 260 km
