At 6 a.m., Luis and Fred left Park A and drove towards Park B at average speeds of 79 km/h and 59 km/h respectively. Upon reaching Park B, Luis rested for 2 hours. He then headed back for Park A at an average speed of 79 km/h along the same route. Luis and Fred met each other on their way at 2 p.m.
- How far had Luis covered when he met Fred on the way?
- How far apart were the two parks?
(a)
Time taken by Fred = 8 h
Time taken by Luis = 8 - 2 = 6 h
Distance covered by Luis when he met Fred
= 6 x 79
= 474 km
(b)
Distance travelled by Fred
= 8 x 59
= 472 km
Distance of the two parks
= (474 + 472) ÷ 2
= 946 ÷ 2
= 473 km
Answer(s): (a) 474 km; (b) 473 km
