At 7 a.m., Paul and Ian left Park C and drove towards Park D at average speeds of 92 km/h and 64 km/h respectively. Upon reaching Park D, Paul rested for 3 hours. He then headed back for Park C at an average speed of 92 km/h along the same route. Paul and Ian met each other on their way at 1 p.m.
- How far had Paul covered when he met Ian on the way?
- How far apart were the two parks?
(a)
Time taken by Ian = 6 h
Time taken by Paul = 6 - 3 = 3 h
Distance covered by Paul when he met Ian
= 3 x 92
= 276 km
(b)
Distance travelled by Ian
= 6 x 64
= 384 km
Distance of the two parks
= (276 + 384) ÷ 2
= 660 ÷ 2
= 330 km
Answer(s): (a) 276 km; (b) 330 km
