At 9 a.m., Luis and Carl left Park T and drove towards Park U at average speeds of 98 km/h and 62 km/h respectively. Upon reaching Park U, Luis rested for 3 hours. He then headed back for Park T at an average speed of 98 km/h along the same route. Luis and Carl met each other on their way at 1 p.m.
- How far had Luis covered when he met Carl on the way?
- How far apart were the two parks?
(a)
Time taken by Carl = 4 h
Time taken by Luis = 4 - 3 = 1 h
Distance covered by Luis when he met Carl
= 1 x 98
= 98 km
(b)
Distance travelled by Carl
= 4 x 62
= 248 km
Distance of the two parks
= (98 + 248) ÷ 2
= 346 ÷ 2
= 173 km
Answer(s): (a) 98 km; (b) 173 km
