At 8 a.m., Archie and Will left Park U and drove towards Park V at average speeds of 71 km/h and 51 km/h respectively. Upon reaching Park V, Archie rested for 2 hours. He then headed back for Park U at an average speed of 71 km/h along the same route. Archie and Will met each other on their way at 2 p.m.
- How far had Archie covered when he met Will on the way?
- How far apart were the two parks?
(a)
Time taken by Will = 6 h
Time taken by Archie = 6 - 2 = 4 h
Distance covered by Archie when he met Will
= 4 x 71
= 284 km
(b)
Distance travelled by Will
= 6 x 51
= 306 km
Distance of the two parks
= (284 + 306) ÷ 2
= 590 ÷ 2
= 295 km
Answer(s): (a) 284 km; (b) 295 km
