At 6 a.m., Ivan and Wesley left Park B and drove towards Park C at average speeds of 80 km/h and 64 km/h respectively. Upon reaching Park C, Ivan rested for 3 hours. He then headed back for Park B at an average speed of 80 km/h along the same route. Ivan and Wesley met each other on their way at 12 noon.
- How far had Ivan 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 Ivan = 6 - 3 = 3 h
Distance covered by Ivan when he met Wesley
= 3 x 80
= 240 km
(b)
Distance travelled by Wesley
= 6 x 64
= 384 km
Distance of the two parks
= (240 + 384) ÷ 2
= 624 ÷ 2
= 312 km
Answer(s): (a) 240 km; (b) 312 km
