At 9 a.m., Jeremy and Paul left Park N and drove towards Park P at average speeds of 88 km/h and 63 km/h respectively. Upon reaching Park P, Jeremy rested for 2 hours. He then headed back for Park N at an average speed of 88 km/h along the same route. Jeremy and Paul met each other on their way at 1 p.m.
- How far had Jeremy covered when he met Paul on the way?
- How far apart were the two parks?
(a)
Time taken by Paul = 4 h
Time taken by Jeremy = 4 - 2 = 2 h
Distance covered by Jeremy when he met Paul
= 2 x 88
= 176 km
(b)
Distance travelled by Paul
= 4 x 63
= 252 km
Distance of the two parks
= (176 + 252) ÷ 2
= 428 ÷ 2
= 214 km
Answer(s): (a) 176 km; (b) 214 km
