At 5 a.m., John and George left Park C and drove towards Park D at average speeds of 70 km/h and 58 km/h respectively. Upon reaching Park D, John rested for 3 hours. He then headed back for Park C at an average speed of 70 km/h along the same route. John and George met each other on their way at 2 p.m.
- How far had John covered when he met George on the way?
- How far apart were the two parks?
(a)
Time taken by George = 9 h
Time taken by John = 9 - 3 = 6 h
Distance covered by John when he met George
= 6 x 70
= 420 km
(b)
Distance travelled by George
= 9 x 58
= 522 km
Distance of the two parks
= (420 + 522) ÷ 2
= 942 ÷ 2
= 471 km
Answer(s): (a) 420 km; (b) 471 km
