At 8 a.m., Vaidev and Paul left Park N and drove towards Park P at average speeds of 70 km/h and 61 km/h respectively. Upon reaching Park P, Vaidev rested for 2 hours. He then headed back for Park N at an average speed of 70 km/h along the same route. Vaidev and Paul met each other on their way at 2 p.m.
- How far had Vaidev covered when he met Paul on the way?
- How far apart were the two parks?
(a)
Time taken by Paul = 6 h
Time taken by Vaidev = 6 - 2 = 4 h
Distance covered by Vaidev when he met Paul
= 4 x 70
= 280 km
(b)
Distance travelled by Paul
= 6 x 61
= 366 km
Distance of the two parks
= (280 + 366) ÷ 2
= 646 ÷ 2
= 323 km
Answer(s): (a) 280 km; (b) 323 km
