At 6 a.m., Flynn and Mark left Park P and drove towards Park Q at average speeds of 90 km/h and 53 km/h respectively. Upon reaching Park Q, Flynn rested for 2 hours. He then headed back for Park P at an average speed of 90 km/h along the same route. Flynn and Mark met each other on their way at 12 noon.
- How far had Flynn covered when he met Mark on the way?
- How far apart were the two parks?
(a)
Time taken by Mark = 6 h
Time taken by Flynn = 6 - 2 = 4 h
Distance covered by Flynn when he met Mark
= 4 x 90
= 360 km
(b)
Distance travelled by Mark
= 6 x 53
= 318 km
Distance of the two parks
= (360 + 318) ÷ 2
= 678 ÷ 2
= 339 km
Answer(s): (a) 360 km; (b) 339 km
