At 6 a.m., Ian and Tim left Park Z and drove towards Park A at average speeds of 96 km/h and 61 km/h respectively. Upon reaching Park A, Ian rested for 2 hours. He then headed back for Park Z at an average speed of 96 km/h along the same route. Ian and Tim met each other on their way at 2 p.m.
- How far had Ian covered when he met Tim on the way?
- How far apart were the two parks?
(a)
Time taken by Tim = 8 h
Time taken by Ian = 8 - 2 = 6 h
Distance covered by Ian when he met Tim
= 6 x 96
= 576 km
(b)
Distance travelled by Tim
= 8 x 61
= 488 km
Distance of the two parks
= (576 + 488) ÷ 2
= 1064 ÷ 2
= 532 km
Answer(s): (a) 576 km; (b) 532 km
