At 7 a.m., Jeremy and Ahmad left Park B and drove towards Park C at average speeds of 78 km/h and 62 km/h respectively. Upon reaching Park C, Jeremy rested for 2 hours. He then headed back for Park B at an average speed of 78 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 = 5 h
Time taken by Jeremy = 5 - 2 = 3 h
Distance covered by Jeremy when he met Ahmad
= 3 x 78
= 234 km
(b)
Distance travelled by Ahmad
= 5 x 62
= 310 km
Distance of the two parks
= (234 + 310) ÷ 2
= 544 ÷ 2
= 272 km
Answer(s): (a) 234 km; (b) 272 km
