At 6 a.m., Ahmad and Eric left Park K and drove towards Park L at average speeds of 91 km/h and 65 km/h respectively. Upon reaching Park L, Ahmad rested for 2 hours. He then headed back for Park K at an average speed of 91 km/h along the same route. Ahmad and Eric met each other on their way at 1 p.m.
- How far had Ahmad covered when he met Eric on the way?
- How far apart were the two parks?
(a)
Time taken by Eric = 7 h
Time taken by Ahmad = 7 - 2 = 5 h
Distance covered by Ahmad when he met Eric
= 5 x 91
= 455 km
(b)
Distance travelled by Eric
= 7 x 65
= 455 km
Distance of the two parks
= (455 + 455) ÷ 2
= 910 ÷ 2
= 455 km
Answer(s): (a) 455 km; (b) 455 km
