At 6 a.m., Sean and Cole left Park L and drove towards Park M at average speeds of 83 km/h and 52 km/h respectively. Upon reaching Park M, Sean rested for 2 hours. He then headed back for Park L at an average speed of 83 km/h along the same route. Sean and Cole met each other on their way at 12 noon.
- How far had Sean covered when he met Cole on the way?
- How far apart were the two parks?
(a)
Time taken by Cole = 6 h
Time taken by Sean = 6 - 2 = 4 h
Distance covered by Sean when he met Cole
= 4 x 83
= 332 km
(b)
Distance travelled by Cole
= 6 x 52
= 312 km
Distance of the two parks
= (332 + 312) ÷ 2
= 644 ÷ 2
= 322 km
Answer(s): (a) 332 km; (b) 322 km
