At 5 a.m., Justin and Flynn left Park V and drove towards Park W at average speeds of 74 km/h and 60 km/h respectively. Upon reaching Park W, Justin rested for 3 hours. He then headed back for Park V at an average speed of 74 km/h along the same route. Justin and Flynn met each other on their way at 12 noon.
- How far had Justin covered when he met Flynn on the way?
- How far apart were the two parks?
(a)
Time taken by Flynn = 7 h
Time taken by Justin = 7 - 3 = 4 h
Distance covered by Justin when he met Flynn
= 4 x 74
= 296 km
(b)
Distance travelled by Flynn
= 7 x 60
= 420 km
Distance of the two parks
= (296 + 420) ÷ 2
= 716 ÷ 2
= 358 km
Answer(s): (a) 296 km; (b) 358 km
