At 7 a.m., George and Liam left Park D and drove towards Park E at average speeds of 83 km/h and 52 km/h respectively. Upon reaching Park E, George rested for 3 hours. He then headed back for Park D at an average speed of 83 km/h along the same route. George and Liam met each other on their way at 12 noon.
- How far had George covered when he met Liam on the way?
- How far apart were the two parks?
(a)
Time taken by Liam = 5 h
Time taken by George = 5 - 3 = 2 h
Distance covered by George when he met Liam
= 2 x 83
= 166 km
(b)
Distance travelled by Liam
= 5 x 52
= 260 km
Distance of the two parks
= (166 + 260) ÷ 2
= 426 ÷ 2
= 213 km
Answer(s): (a) 166 km; (b) 213 km
