At 7 a.m., Paul and Peter left Park W and drove towards Park X at average speeds of 79 km/h and 54 km/h respectively. Upon reaching Park X, Paul rested for 3 hours. He then headed back for Park W at an average speed of 79 km/h along the same route. Paul and Peter met each other on their way at 2 p.m.
- How far had Paul 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 Paul = 7 - 3 = 4 h
Distance covered by Paul when he met Peter
= 4 x 79
= 316 km
(b)
Distance travelled by Peter
= 7 x 54
= 378 km
Distance of the two parks
= (316 + 378) ÷ 2
= 694 ÷ 2
= 347 km
Answer(s): (a) 316 km; (b) 347 km
