At 8 a.m., Andy and Luis left Park M and drove towards Park N at average speeds of 97 km/h and 54 km/h respectively. Upon reaching Park N, Andy rested for 3 hours. He then headed back for Park M at an average speed of 97 km/h along the same route. Andy and Luis met each other on their way at 1 p.m.
- How far had Andy covered when he met Luis on the way?
- How far apart were the two parks?
(a)
Time taken by Luis = 5 h
Time taken by Andy = 5 - 3 = 2 h
Distance covered by Andy when he met Luis
= 2 x 97
= 194 km
(b)
Distance travelled by Luis
= 5 x 54
= 270 km
Distance of the two parks
= (194 + 270) ÷ 2
= 464 ÷ 2
= 232 km
Answer(s): (a) 194 km; (b) 232 km
