At 7 a.m., Peter and Warren left Park D and drove towards Park E at average speeds of 88 km/h and 50 km/h respectively. Upon reaching Park E, Peter rested for 3 hours. He then headed back for Park D at an average speed of 88 km/h along the same route. Peter and Warren met each other on their way at 12 noon.
- How far had Peter 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 Peter = 5 - 3 = 2 h
Distance covered by Peter when he met Warren
= 2 x 88
= 176 km
(b)
Distance travelled by Warren
= 5 x 50
= 250 km
Distance of the two parks
= (176 + 250) ÷ 2
= 426 ÷ 2
= 213 km
Answer(s): (a) 176 km; (b) 213 km
