At 7 a.m., Perry and Lee left Park G and drove towards Park H at average speeds of 93 km/h and 62 km/h respectively. Upon reaching Park H, Perry rested for 3 hours. He then headed back for Park G at an average speed of 93 km/h along the same route. Perry and Lee met each other on their way at 12 noon.
- How far had Perry covered when he met Lee on the way?
- How far apart were the two parks?
(a)
Time taken by Lee = 5 h
Time taken by Perry = 5 - 3 = 2 h
Distance covered by Perry when he met Lee
= 2 x 93
= 186 km
(b)
Distance travelled by Lee
= 5 x 62
= 310 km
Distance of the two parks
= (186 + 310) ÷ 2
= 496 ÷ 2
= 248 km
Answer(s): (a) 186 km; (b) 248 km
