At 6 a.m., Michael and Vaidev left Park M and drove towards Park N at average speeds of 84 km/h and 65 km/h respectively. Upon reaching Park N, Michael rested for 2 hours. He then headed back for Park M at an average speed of 84 km/h along the same route. Michael and Vaidev met each other on their way at 12 noon.
- How far had Michael covered when he met Vaidev on the way?
- How far apart were the two parks?
(a)
Time taken by Vaidev = 6 h
Time taken by Michael = 6 - 2 = 4 h
Distance covered by Michael when he met Vaidev
= 4 x 84
= 336 km
(b)
Distance travelled by Vaidev
= 6 x 65
= 390 km
Distance of the two parks
= (336 + 390) ÷ 2
= 726 ÷ 2
= 363 km
Answer(s): (a) 336 km; (b) 363 km
