At 7 a.m., Carl and Vincent left Park W and drove towards Park X at average speeds of 89 km/h and 65 km/h respectively. Upon reaching Park X, Carl rested for 2 hours. He then headed back for Park W at an average speed of 89 km/h along the same route. Carl and Vincent met each other on their way at 1 p.m.
- How far had Carl covered when he met Vincent on the way?
- How far apart were the two parks?
(a)
Time taken by Vincent = 6 h
Time taken by Carl = 6 - 2 = 4 h
Distance covered by Carl when he met Vincent
= 4 x 89
= 356 km
(b)
Distance travelled by Vincent
= 6 x 65
= 390 km
Distance of the two parks
= (356 + 390) ÷ 2
= 746 ÷ 2
= 373 km
Answer(s): (a) 356 km; (b) 373 km
