At 9 a.m., Perry and Glen left Park X and drove towards Park Y at average speeds of 74 km/h and 60 km/h respectively. Upon reaching Park Y, Perry rested for 2 hours. He then headed back for Park X at an average speed of 74 km/h along the same route. Perry and Glen met each other on their way at 1 p.m.
- How far had Perry covered when he met Glen on the way?
- How far apart were the two parks?
(a)
Time taken by Glen = 4 h
Time taken by Perry = 4 - 2 = 2 h
Distance covered by Perry when he met Glen
= 2 x 74
= 148 km
(b)
Distance travelled by Glen
= 4 x 60
= 240 km
Distance of the two parks
= (148 + 240) ÷ 2
= 388 ÷ 2
= 194 km
Answer(s): (a) 148 km; (b) 194 km
