At 9 a.m., Vincent and Simon left Park J and drove towards Park K at average speeds of 74 km/h and 63 km/h respectively. Upon reaching Park K, Vincent rested for 2 hours. He then headed back for Park J at an average speed of 74 km/h along the same route. Vincent and Simon met each other on their way at 1 p.m.
- How far had Vincent covered when he met Simon on the way?
- How far apart were the two parks?
(a)
Time taken by Simon = 4 h
Time taken by Vincent = 4 - 2 = 2 h
Distance covered by Vincent when he met Simon
= 2 x 74
= 148 km
(b)
Distance travelled by Simon
= 4 x 63
= 252 km
Distance of the two parks
= (148 + 252) ÷ 2
= 400 ÷ 2
= 200 km
Answer(s): (a) 148 km; (b) 200 km
