At 6 a.m., Bryan and Billy left Park V and drove towards Park W at average speeds of 93 km/h and 52 km/h respectively. Upon reaching Park W, Bryan rested for 2 hours. He then headed back for Park V at an average speed of 93 km/h along the same route. Bryan and Billy met each other on their way at 12 noon.
- How far had Bryan covered when he met Billy on the way?
- How far apart were the two parks?
(a)
Time taken by Billy = 6 h
Time taken by Bryan = 6 - 2 = 4 h
Distance covered by Bryan when he met Billy
= 4 x 93
= 372 km
(b)
Distance travelled by Billy
= 6 x 52
= 312 km
Distance of the two parks
= (372 + 312) ÷ 2
= 684 ÷ 2
= 342 km
Answer(s): (a) 372 km; (b) 342 km
