At 5 a.m., Ian and Peter left Park T and drove towards Park U at average speeds of 93 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 93 km/h along the same route. Ian and Peter met each other on their way at 12 noon.
- How far had Ian covered when he met Peter on the way?
- How far apart were the two parks?
(a)
Time taken by Peter = 7 h
Time taken by Ian = 7 - 3 = 4 h
Distance covered by Ian when he met Peter
= 4 x 93
= 372 km
(b)
Distance travelled by Peter
= 7 x 58
= 406 km
Distance of the two parks
= (372 + 406) ÷ 2
= 778 ÷ 2
= 389 km
Answer(s): (a) 372 km; (b) 389 km
