At 6 a.m., John and Peter left Park K and drove towards Park L at average speeds of 70 km/h and 61 km/h respectively. Upon reaching Park L, John rested for 2 hours. He then headed back for Park K at an average speed of 70 km/h along the same route. John and Peter met each other on their way at 12 noon.
- How far had John covered when he met Peter on the way?
- How far apart were the two parks?
(a)
Time taken by Peter = 6 h
Time taken by John = 6 - 2 = 4 h
Distance covered by John when he met Peter
= 4 x 70
= 280 km
(b)
Distance travelled by Peter
= 6 x 61
= 366 km
Distance of the two parks
= (280 + 366) ÷ 2
= 646 ÷ 2
= 323 km
Answer(s): (a) 280 km; (b) 323 km
