At 6 a.m., George and Bobby left Park D and drove towards Park E at average speeds of 76 km/h and 50 km/h respectively. Upon reaching Park E, George rested for 2 hours. He then headed back for Park D at an average speed of 76 km/h along the same route. George and Bobby met each other on their way at 12 noon.
- How far had George covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 6 h
Time taken by George = 6 - 2 = 4 h
Distance covered by George when he met Bobby
= 4 x 76
= 304 km
(b)
Distance travelled by Bobby
= 6 x 50
= 300 km
Distance of the two parks
= (304 + 300) ÷ 2
= 604 ÷ 2
= 302 km
Answer(s): (a) 304 km; (b) 302 km
