At 6 a.m., Perry and Tim left Park B and drove towards Park C at average speeds of 71 km/h and 51 km/h respectively. Upon reaching Park C, Perry rested for 2 hours. He then headed back for Park B at an average speed of 71 km/h along the same route. Perry and Tim met each other on their way at 12 noon.
- How far had Perry covered when he met Tim on the way?
- How far apart were the two parks?
(a)
Time taken by Tim = 6 h
Time taken by Perry = 6 - 2 = 4 h
Distance covered by Perry when he met Tim
= 4 x 71
= 284 km
(b)
Distance travelled by Tim
= 6 x 51
= 306 km
Distance of the two parks
= (284 + 306) ÷ 2
= 590 ÷ 2
= 295 km
Answer(s): (a) 284 km; (b) 295 km
