At 7 a.m., Brandon and Sam left Park S and drove towards Park T at average speeds of 94 km/h and 64 km/h respectively. Upon reaching Park T, Brandon rested for 2 hours. He then headed back for Park S at an average speed of 94 km/h along the same route. Brandon and Sam met each other on their way at 12 noon.
- How far had Brandon covered when he met Sam on the way?
- How far apart were the two parks?
(a)
Time taken by Sam = 5 h
Time taken by Brandon = 5 - 2 = 3 h
Distance covered by Brandon when he met Sam
= 3 x 94
= 282 km
(b)
Distance travelled by Sam
= 5 x 64
= 320 km
Distance of the two parks
= (282 + 320) ÷ 2
= 602 ÷ 2
= 301 km
Answer(s): (a) 282 km; (b) 301 km
