At 6 a.m., Sean and Vincent left Park V and drove towards Park W at average speeds of 88 km/h and 57 km/h respectively. Upon reaching Park W, Sean rested for 3 hours. He then headed back for Park V at an average speed of 88 km/h along the same route. Sean and Vincent met each other on their way at 12 noon.
- How far had Sean 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 Sean = 6 - 3 = 3 h
Distance covered by Sean when he met Vincent
= 3 x 88
= 264 km
(b)
Distance travelled by Vincent
= 6 x 57
= 342 km
Distance of the two parks
= (264 + 342) ÷ 2
= 606 ÷ 2
= 303 km
Answer(s): (a) 264 km; (b) 303 km
