At 6 a.m., Albert and Cole left Park L and drove towards Park M at average speeds of 76 km/h and 64 km/h respectively. Upon reaching Park M, Albert rested for 3 hours. He then headed back for Park L at an average speed of 76 km/h along the same route. Albert and Cole met each other on their way at 1 p.m.
- How far had Albert covered when he met Cole on the way?
- How far apart were the two parks?
(a)
Time taken by Cole = 7 h
Time taken by Albert = 7 - 3 = 4 h
Distance covered by Albert when he met Cole
= 4 x 76
= 304 km
(b)
Distance travelled by Cole
= 7 x 64
= 448 km
Distance of the two parks
= (304 + 448) ÷ 2
= 752 ÷ 2
= 376 km
Answer(s): (a) 304 km; (b) 376 km
