At 6 a.m., Ahmad and Ben left Park W and drove towards Park X at average speeds of 76 km/h and 50 km/h respectively. Upon reaching Park X, Ahmad rested for 2 hours. He then headed back for Park W at an average speed of 76 km/h along the same route. Ahmad and Ben met each other on their way at 12 noon.
- How far had Ahmad covered when he met Ben on the way?
- How far apart were the two parks?
(a)
Time taken by Ben = 6 h
Time taken by Ahmad = 6 - 2 = 4 h
Distance covered by Ahmad when he met Ben
= 4 x 76
= 304 km
(b)
Distance travelled by Ben
= 6 x 50
= 300 km
Distance of the two parks
= (304 + 300) ÷ 2
= 604 ÷ 2
= 302 km
Answer(s): (a) 304 km; (b) 302 km
