At 5 a.m., David and Fabian left Park L and drove towards Park M at average speeds of 95 km/h and 53 km/h respectively. Upon reaching Park M, David rested for 2 hours. He then headed back for Park L at an average speed of 95 km/h along the same route. David and Fabian met each other on their way at 12 noon.
- How far had David covered when he met Fabian on the way?
- How far apart were the two parks?
(a)
Time taken by Fabian = 7 h
Time taken by David = 7 - 2 = 5 h
Distance covered by David when he met Fabian
= 5 x 95
= 475 km
(b)
Distance travelled by Fabian
= 7 x 53
= 371 km
Distance of the two parks
= (475 + 371) ÷ 2
= 846 ÷ 2
= 423 km
Answer(s): (a) 475 km; (b) 423 km
