At 6 a.m., Ian and Wesley left Park K and drove towards Park L at average speeds of 97 km/h and 59 km/h respectively. Upon reaching Park L, Ian rested for 2 hours. He then headed back for Park K at an average speed of 97 km/h along the same route. Ian and Wesley met each other on their way at 12 noon.
- How far had Ian covered when he met Wesley on the way?
- How far apart were the two parks?
(a)
Time taken by Wesley = 6 h
Time taken by Ian = 6 - 2 = 4 h
Distance covered by Ian when he met Wesley
= 4 x 97
= 388 km
(b)
Distance travelled by Wesley
= 6 x 59
= 354 km
Distance of the two parks
= (388 + 354) ÷ 2
= 742 ÷ 2
= 371 km
Answer(s): (a) 388 km; (b) 371 km
