At 6 a.m., Carl and Luis left Park M and drove towards Park N at average speeds of 72 km/h and 63 km/h respectively. Upon reaching Park N, Carl rested for 2 hours. He then headed back for Park M at an average speed of 72 km/h along the same route. Carl and Luis met each other on their way at 2 p.m.
- How far had Carl covered when he met Luis on the way?
- How far apart were the two parks?
(a)
Time taken by Luis = 8 h
Time taken by Carl = 8 - 2 = 6 h
Distance covered by Carl when he met Luis
= 6 x 72
= 432 km
(b)
Distance travelled by Luis
= 8 x 63
= 504 km
Distance of the two parks
= (432 + 504) ÷ 2
= 936 ÷ 2
= 468 km
Answer(s): (a) 432 km; (b) 468 km
