At 6 a.m., Ivan and Luis left Park M and drove towards Park N at average speeds of 96 km/h and 56 km/h respectively. Upon reaching Park N, Ivan rested for 2 hours. He then headed back for Park M at an average speed of 96 km/h along the same route. Ivan and Luis met each other on their way at 12 noon.
- How far had Ivan covered when he met Luis on the way?
- How far apart were the two parks?
(a)
Time taken by Luis = 6 h
Time taken by Ivan = 6 - 2 = 4 h
Distance covered by Ivan when he met Luis
= 4 x 96
= 384 km
(b)
Distance travelled by Luis
= 6 x 56
= 336 km
Distance of the two parks
= (384 + 336) ÷ 2
= 720 ÷ 2
= 360 km
Answer(s): (a) 384 km; (b) 360 km
