At 6 a.m., John and Will left Park C and drove towards Park D at average speeds of 82 km/h and 53 km/h respectively. Upon reaching Park D, John rested for 3 hours. He then headed back for Park C at an average speed of 82 km/h along the same route. John and Will met each other on their way at 12 noon.
- How far had John covered when he met Will on the way?
- How far apart were the two parks?
(a)
Time taken by Will = 6 h
Time taken by John = 6 - 3 = 3 h
Distance covered by John when he met Will
= 3 x 82
= 246 km
(b)
Distance travelled by Will
= 6 x 53
= 318 km
Distance of the two parks
= (246 + 318) ÷ 2
= 564 ÷ 2
= 282 km
Answer(s): (a) 246 km; (b) 282 km
