At 5 a.m., Andy and Ryan left Park N and drove towards Park P at average speeds of 92 km/h and 62 km/h respectively. Upon reaching Park P, Andy rested for 3 hours. He then headed back for Park N at an average speed of 92 km/h along the same route. Andy and Ryan met each other on their way at 12 noon.
- How far had Andy covered when he met Ryan on the way?
- How far apart were the two parks?
(a)
Time taken by Ryan = 7 h
Time taken by Andy = 7 - 3 = 4 h
Distance covered by Andy when he met Ryan
= 4 x 92
= 368 km
(b)
Distance travelled by Ryan
= 7 x 62
= 434 km
Distance of the two parks
= (368 + 434) ÷ 2
= 802 ÷ 2
= 401 km
Answer(s): (a) 368 km; (b) 401 km
