At 5 a.m., Jeremy and Ahmad left Park U and drove towards Park V at average speeds of 96 km/h and 60 km/h respectively. Upon reaching Park V, Jeremy rested for 2 hours. He then headed back for Park U at an average speed of 96 km/h along the same route. Jeremy and Ahmad met each other on their way at 12 noon.
- How far had Jeremy covered when he met Ahmad on the way?
- How far apart were the two parks?
(a)
Time taken by Ahmad = 7 h
Time taken by Jeremy = 7 - 2 = 5 h
Distance covered by Jeremy when he met Ahmad
= 5 x 96
= 480 km
(b)
Distance travelled by Ahmad
= 7 x 60
= 420 km
Distance of the two parks
= (480 + 420) ÷ 2
= 900 ÷ 2
= 450 km
Answer(s): (a) 480 km; (b) 450 km
