At 9 a.m., Nick and Flynn left Park K and drove towards Park L at average speeds of 86 km/h and 50 km/h respectively. Upon reaching Park L, Nick rested for 3 hours. He then headed back for Park K at an average speed of 86 km/h along the same route. Nick and Flynn met each other on their way at 1 p.m.
- How far had Nick covered when he met Flynn on the way?
- How far apart were the two parks?
(a)
Time taken by Flynn = 4 h
Time taken by Nick = 4 - 3 = 1 h
Distance covered by Nick when he met Flynn
= 1 x 86
= 86 km
(b)
Distance travelled by Flynn
= 4 x 50
= 200 km
Distance of the two parks
= (86 + 200) ÷ 2
= 286 ÷ 2
= 143 km
Answer(s): (a) 86 km; (b) 143 km
