At 9 a.m., Bryan and Fabian left Park L and drove towards Park M at average speeds of 100 km/h and 55 km/h respectively. Upon reaching Park M, Bryan rested for 2 hours. He then headed back for Park L at an average speed of 100 km/h along the same route. Bryan and Fabian met each other on their way at 1 p.m.
- How far had Bryan covered when he met Fabian on the way?
- How far apart were the two parks?
(a)
Time taken by Fabian = 4 h
Time taken by Bryan = 4 - 2 = 2 h
Distance covered by Bryan when he met Fabian
= 2 x 100
= 200 km
(b)
Distance travelled by Fabian
= 4 x 55
= 220 km
Distance of the two parks
= (200 + 220) ÷ 2
= 420 ÷ 2
= 210 km
Answer(s): (a) 200 km; (b) 210 km
