At 7 a.m., Peter and Vincent left Park G and drove towards Park H at average speeds of 96 km/h and 61 km/h respectively. Upon reaching Park H, Peter rested for 2 hours. He then headed back for Park G at an average speed of 96 km/h along the same route. Peter and Vincent met each other on their way at 1 p.m.
- How far had Peter covered when he met Vincent on the way?
- How far apart were the two parks?
(a)
Time taken by Vincent = 6 h
Time taken by Peter = 6 - 2 = 4 h
Distance covered by Peter when he met Vincent
= 4 x 96
= 384 km
(b)
Distance travelled by Vincent
= 6 x 61
= 366 km
Distance of the two parks
= (384 + 366) ÷ 2
= 750 ÷ 2
= 375 km
Answer(s): (a) 384 km; (b) 375 km
