At 5 a.m., Cole and Brandon left Park D and drove towards Park E at average speeds of 82 km/h and 57 km/h respectively. Upon reaching Park E, Cole rested for 3 hours. He then headed back for Park D at an average speed of 82 km/h along the same route. Cole and Brandon met each other on their way at 1 p.m.
- How far had Cole covered when he met Brandon on the way?
- How far apart were the two parks?
(a)
Time taken by Brandon = 8 h
Time taken by Cole = 8 - 3 = 5 h
Distance covered by Cole when he met Brandon
= 5 x 82
= 410 km
(b)
Distance travelled by Brandon
= 8 x 57
= 456 km
Distance of the two parks
= (410 + 456) ÷ 2
= 866 ÷ 2
= 433 km
Answer(s): (a) 410 km; (b) 433 km
