At 6 a.m., Eric and Ahmad left Park F and drove towards Park G at average speeds of 85 km/h and 59 km/h respectively. Upon reaching Park G, Eric rested for 2 hours. He then headed back for Park F at an average speed of 85 km/h along the same route. Eric and Ahmad met each other on their way at 12 noon.
- How far had Eric covered when he met Ahmad on the way?
- How far apart were the two parks?
(a)
Time taken by Ahmad = 6 h
Time taken by Eric = 6 - 2 = 4 h
Distance covered by Eric when he met Ahmad
= 4 x 85
= 340 km
(b)
Distance travelled by Ahmad
= 6 x 59
= 354 km
Distance of the two parks
= (340 + 354) ÷ 2
= 694 ÷ 2
= 347 km
Answer(s): (a) 340 km; (b) 347 km
