At 6 a.m., Vaidev and Andy left Park Y and drove towards Park Z at average speeds of 88 km/h and 61 km/h respectively. Upon reaching Park Z, Vaidev rested for 3 hours. He then headed back for Park Y at an average speed of 88 km/h along the same route. Vaidev and Andy met each other on their way at 12 noon.
- How far had Vaidev covered when he met Andy on the way?
- How far apart were the two parks?
(a)
Time taken by Andy = 6 h
Time taken by Vaidev = 6 - 3 = 3 h
Distance covered by Vaidev when he met Andy
= 3 x 88
= 264 km
(b)
Distance travelled by Andy
= 6 x 61
= 366 km
Distance of the two parks
= (264 + 366) ÷ 2
= 630 ÷ 2
= 315 km
Answer(s): (a) 264 km; (b) 315 km
