At 7 a.m., John and Simon left Park F and drove towards Park G at average speeds of 86 km/h and 50 km/h respectively. Upon reaching Park G, John rested for 2 hours. He then headed back for Park F at an average speed of 86 km/h along the same route. John and Simon met each other on their way at 12 noon.
- How far had John covered when he met Simon on the way?
- How far apart were the two parks?
(a)
Time taken by Simon = 5 h
Time taken by John = 5 - 2 = 3 h
Distance covered by John when he met Simon
= 3 x 86
= 258 km
(b)
Distance travelled by Simon
= 5 x 50
= 250 km
Distance of the two parks
= (258 + 250) ÷ 2
= 508 ÷ 2
= 254 km
Answer(s): (a) 258 km; (b) 254 km
