At 8 a.m., Archie and Billy left Park K and drove towards Park L at average speeds of 93 km/h and 56 km/h respectively. Upon reaching Park L, Archie rested for 2 hours. He then headed back for Park K at an average speed of 93 km/h along the same route. Archie and Billy met each other on their way at 2 p.m.
- How far had Archie 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 Archie = 6 - 2 = 4 h
Distance covered by Archie when he met Billy
= 4 x 93
= 372 km
(b)
Distance travelled by Billy
= 6 x 56
= 336 km
Distance of the two parks
= (372 + 336) ÷ 2
= 708 ÷ 2
= 354 km
Answer(s): (a) 372 km; (b) 354 km
