At 7 a.m., Ian and Warren left Park T and drove towards Park U at average speeds of 75 km/h and 58 km/h respectively. Upon reaching Park U, Ian rested for 3 hours. He then headed back for Park T at an average speed of 75 km/h along the same route. Ian and Warren met each other on their way at 12 noon.
- How far had Ian covered when he met Warren on the way?
- How far apart were the two parks?
(a)
Time taken by Warren = 5 h
Time taken by Ian = 5 - 3 = 2 h
Distance covered by Ian when he met Warren
= 2 x 75
= 150 km
(b)
Distance travelled by Warren
= 5 x 58
= 290 km
Distance of the two parks
= (150 + 290) ÷ 2
= 440 ÷ 2
= 220 km
Answer(s): (a) 150 km; (b) 220 km
