At 7 a.m., Paul and Charlie left Park R and drove towards Park S at average speeds of 95 km/h and 65 km/h respectively. Upon reaching Park S, Paul rested for 2 hours. He then headed back for Park R at an average speed of 95 km/h along the same route. Paul and Charlie met each other on their way at 2 p.m.
- How far had Paul covered when he met Charlie on the way?
- How far apart were the two parks?
(a)
Time taken by Charlie = 7 h
Time taken by Paul = 7 - 2 = 5 h
Distance covered by Paul when he met Charlie
= 5 x 95
= 475 km
(b)
Distance travelled by Charlie
= 7 x 65
= 455 km
Distance of the two parks
= (475 + 455) ÷ 2
= 930 ÷ 2
= 465 km
Answer(s): (a) 475 km; (b) 465 km
