At 7 a.m., Sam and Ryan left Park Y and drove towards Park Z at average speeds of 92 km/h and 52 km/h respectively. Upon reaching Park Z, Sam rested for 2 hours. He then headed back for Park Y at an average speed of 92 km/h along the same route. Sam and Ryan met each other on their way at 12 noon.
- How far had Sam covered when he met Ryan on the way?
- How far apart were the two parks?
(a)
Time taken by Ryan = 5 h
Time taken by Sam = 5 - 2 = 3 h
Distance covered by Sam when he met Ryan
= 3 x 92
= 276 km
(b)
Distance travelled by Ryan
= 5 x 52
= 260 km
Distance of the two parks
= (276 + 260) ÷ 2
= 536 ÷ 2
= 268 km
Answer(s): (a) 276 km; (b) 268 km
