At 7 a.m., Perry and Sean left Park F and drove towards Park G at average speeds of 86 km/h and 58 km/h respectively. Upon reaching Park G, Perry rested for 2 hours. He then headed back for Park F at an average speed of 86 km/h along the same route. Perry and Sean met each other on their way at 1 p.m.
- How far had Perry covered when he met Sean on the way?
- How far apart were the two parks?
(a)
Time taken by Sean = 6 h
Time taken by Perry = 6 - 2 = 4 h
Distance covered by Perry when he met Sean
= 4 x 86
= 344 km
(b)
Distance travelled by Sean
= 6 x 58
= 348 km
Distance of the two parks
= (344 + 348) ÷ 2
= 692 ÷ 2
= 346 km
Answer(s): (a) 344 km; (b) 346 km
