At 7 a.m., Brandon and Lee left Park E and drove towards Park F at average speeds of 79 km/h and 55 km/h respectively. Upon reaching Park F, Brandon rested for 2 hours. He then headed back for Park E at an average speed of 79 km/h along the same route. Brandon and Lee met each other on their way at 12 noon.
- How far had Brandon covered when he met Lee on the way?
- How far apart were the two parks?
(a)
Time taken by Lee = 5 h
Time taken by Brandon = 5 - 2 = 3 h
Distance covered by Brandon when he met Lee
= 3 x 79
= 237 km
(b)
Distance travelled by Lee
= 5 x 55
= 275 km
Distance of the two parks
= (237 + 275) ÷ 2
= 512 ÷ 2
= 256 km
Answer(s): (a) 237 km; (b) 256 km
