At 6 a.m., Ivan and Flynn left Park Z and drove towards Park A at average speeds of 91 km/h and 51 km/h respectively. Upon reaching Park A, Ivan rested for 2 hours. He then headed back for Park Z at an average speed of 91 km/h along the same route. Ivan and Flynn met each other on their way at 12 noon.
- How far had Ivan covered when he met Flynn on the way?
- How far apart were the two parks?
(a)
Time taken by Flynn = 6 h
Time taken by Ivan = 6 - 2 = 4 h
Distance covered by Ivan when he met Flynn
= 4 x 91
= 364 km
(b)
Distance travelled by Flynn
= 6 x 51
= 306 km
Distance of the two parks
= (364 + 306) ÷ 2
= 670 ÷ 2
= 335 km
Answer(s): (a) 364 km; (b) 335 km
