At 7 a.m., Andy and Ryan left Park X and drove towards Park Y at average speeds of 88 km/h and 50 km/h respectively. Upon reaching Park Y, Andy rested for 2 hours. He then headed back for Park X at an average speed of 88 km/h along the same route. Andy and Ryan met each other on their way at 1 p.m.
- How far had Andy covered when he met Ryan on the way?
- How far apart were the two parks?
(a)
Time taken by Ryan = 6 h
Time taken by Andy = 6 - 2 = 4 h
Distance covered by Andy when he met Ryan
= 4 x 88
= 352 km
(b)
Distance travelled by Ryan
= 6 x 50
= 300 km
Distance of the two parks
= (352 + 300) ÷ 2
= 652 ÷ 2
= 326 km
Answer(s): (a) 352 km; (b) 326 km
