At 7 a.m., Fred and Bobby left Park E and drove towards Park F at average speeds of 96 km/h and 62 km/h respectively. Upon reaching Park F, Fred rested for 3 hours. He then headed back for Park E at an average speed of 96 km/h along the same route. Fred and Bobby met each other on their way at 12 noon.
- How far had Fred covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 5 h
Time taken by Fred = 5 - 3 = 2 h
Distance covered by Fred when he met Bobby
= 2 x 96
= 192 km
(b)
Distance travelled by Bobby
= 5 x 62
= 310 km
Distance of the two parks
= (192 + 310) ÷ 2
= 502 ÷ 2
= 251 km
Answer(s): (a) 192 km; (b) 251 km
