At 7 a.m., Ben and Albert left Park D and drove towards Park E at average speeds of 93 km/h and 65 km/h respectively. Upon reaching Park E, Ben rested for 2 hours. He then headed back for Park D at an average speed of 93 km/h along the same route. Ben and Albert met each other on their way at 12 noon.
- How far had Ben covered when he met Albert on the way?
- How far apart were the two parks?
(a)
Time taken by Albert = 5 h
Time taken by Ben = 5 - 2 = 3 h
Distance covered by Ben when he met Albert
= 3 x 93
= 279 km
(b)
Distance travelled by Albert
= 5 x 65
= 325 km
Distance of the two parks
= (279 + 325) ÷ 2
= 604 ÷ 2
= 302 km
Answer(s): (a) 279 km; (b) 302 km
