At 5 a.m., George and Ahmad left Park W and drove towards Park X at average speeds of 84 km/h and 55 km/h respectively. Upon reaching Park X, George rested for 3 hours. He then headed back for Park W at an average speed of 84 km/h along the same route. George and Ahmad met each other on their way at 1 p.m.
- How far had George covered when he met Ahmad on the way?
- How far apart were the two parks?
(a)
Time taken by Ahmad = 8 h
Time taken by George = 8 - 3 = 5 h
Distance covered by George when he met Ahmad
= 5 x 84
= 420 km
(b)
Distance travelled by Ahmad
= 8 x 55
= 440 km
Distance of the two parks
= (420 + 440) ÷ 2
= 860 ÷ 2
= 430 km
Answer(s): (a) 420 km; (b) 430 km
