At 5 a.m., Vaidev and Flynn left Park V and drove towards Park W at average speeds of 97 km/h and 64 km/h respectively. Upon reaching Park W, Vaidev rested for 3 hours. He then headed back for Park V at an average speed of 97 km/h along the same route. Vaidev and Flynn met each other on their way at 12 noon.
- How far had Vaidev 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 Vaidev = 7 - 3 = 4 h
Distance covered by Vaidev when he met Flynn
= 4 x 97
= 388 km
(b)
Distance travelled by Flynn
= 7 x 64
= 448 km
Distance of the two parks
= (388 + 448) ÷ 2
= 836 ÷ 2
= 418 km
Answer(s): (a) 388 km; (b) 418 km
