At 7 a.m., George and Tommy left Park D and drove towards Park E at average speeds of 76 km/h and 64 km/h respectively. Upon reaching Park E, George rested for 3 hours. He then headed back for Park D at an average speed of 76 km/h along the same route. George and Tommy met each other on their way at 12 noon.
- How far had George covered when he met Tommy on the way?
- How far apart were the two parks?
(a)
Time taken by Tommy = 5 h
Time taken by George = 5 - 3 = 2 h
Distance covered by George when he met Tommy
= 2 x 76
= 152 km
(b)
Distance travelled by Tommy
= 5 x 64
= 320 km
Distance of the two parks
= (152 + 320) ÷ 2
= 472 ÷ 2
= 236 km
Answer(s): (a) 152 km; (b) 236 km
