At 5 a.m., Flynn and Vaidev left Park Q and drove towards Park R at average speeds of 84 km/h and 61 km/h respectively. Upon reaching Park R, Flynn rested for 3 hours. He then headed back for Park Q at an average speed of 84 km/h along the same route. Flynn and Vaidev met each other on their way at 1 p.m.
- How far had Flynn covered when he met Vaidev on the way?
- How far apart were the two parks?
(a)
Time taken by Vaidev = 8 h
Time taken by Flynn = 8 - 3 = 5 h
Distance covered by Flynn when he met Vaidev
= 5 x 84
= 420 km
(b)
Distance travelled by Vaidev
= 8 x 61
= 488 km
Distance of the two parks
= (420 + 488) ÷ 2
= 908 ÷ 2
= 454 km
Answer(s): (a) 420 km; (b) 454 km
