At 7 a.m., Vincent and Sean left Park J and drove towards Park K at average speeds of 86 km/h and 52 km/h respectively. Upon reaching Park K, Vincent rested for 2 hours. He then headed back for Park J at an average speed of 86 km/h along the same route. Vincent and Sean met each other on their way at 1 p.m.
- How far had Vincent covered when he met Sean on the way?
- How far apart were the two parks?
(a)
Time taken by Sean = 6 h
Time taken by Vincent = 6 - 2 = 4 h
Distance covered by Vincent when he met Sean
= 4 x 86
= 344 km
(b)
Distance travelled by Sean
= 6 x 52
= 312 km
Distance of the two parks
= (344 + 312) ÷ 2
= 656 ÷ 2
= 328 km
Answer(s): (a) 344 km; (b) 328 km
