At 8 a.m., Luke and Andy left Park N and drove towards Park P at average speeds of 85 km/h and 62 km/h respectively. Upon reaching Park P, Luke rested for 2 hours. He then headed back for Park N at an average speed of 85 km/h along the same route. Luke and Andy met each other on their way at 2 p.m.
- How far had Luke covered when he met Andy on the way?
- How far apart were the two parks?
(a)
Time taken by Andy = 6 h
Time taken by Luke = 6 - 2 = 4 h
Distance covered by Luke when he met Andy
= 4 x 85
= 340 km
(b)
Distance travelled by Andy
= 6 x 62
= 372 km
Distance of the two parks
= (340 + 372) ÷ 2
= 712 ÷ 2
= 356 km
Answer(s): (a) 340 km; (b) 356 km
