At 7 a.m., Pierre and Billy left Park V and drove towards Park W at average speeds of 76 km/h and 62 km/h respectively. Upon reaching Park W, Pierre rested for 2 hours. He then headed back for Park V at an average speed of 76 km/h along the same route. Pierre and Billy met each other on their way at 1 p.m.
- How far had Pierre 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 Pierre = 6 - 2 = 4 h
Distance covered by Pierre when he met Billy
= 4 x 76
= 304 km
(b)
Distance travelled by Billy
= 6 x 62
= 372 km
Distance of the two parks
= (304 + 372) ÷ 2
= 676 ÷ 2
= 338 km
Answer(s): (a) 304 km; (b) 338 km
