At 7 a.m., Ahmad and Ian left Park X and drove towards Park Y at average speeds of 94 km/h and 63 km/h respectively. Upon reaching Park Y, Ahmad rested for 2 hours. He then headed back for Park X at an average speed of 94 km/h along the same route. Ahmad and Ian met each other on their way at 1 p.m.
- How far had Ahmad 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 Ahmad = 6 - 2 = 4 h
Distance covered by Ahmad when he met Ian
= 4 x 94
= 376 km
(b)
Distance travelled by Ian
= 6 x 63
= 378 km
Distance of the two parks
= (376 + 378) ÷ 2
= 754 ÷ 2
= 377 km
Answer(s): (a) 376 km; (b) 377 km
