At 5 a.m., Daniel and George left Park N and drove towards Park P at average speeds of 95 km/h and 65 km/h respectively. Upon reaching Park P, Daniel rested for 2 hours. He then headed back for Park N at an average speed of 95 km/h along the same route. Daniel and George met each other on their way at 2 p.m.
- How far had Daniel covered when he met George on the way?
- How far apart were the two parks?
(a)
Time taken by George = 9 h
Time taken by Daniel = 9 - 2 = 7 h
Distance covered by Daniel when he met George
= 7 x 95
= 665 km
(b)
Distance travelled by George
= 9 x 65
= 585 km
Distance of the two parks
= (665 + 585) ÷ 2
= 1250 ÷ 2
= 625 km
Answer(s): (a) 665 km; (b) 625 km
