At 6 a.m., Vincent and Eric left Park M and drove towards Park N at average speeds of 70 km/h and 62 km/h respectively. Upon reaching Park N, Vincent rested for 3 hours. He then headed back for Park M at an average speed of 70 km/h along the same route. Vincent and Eric met each other on their way at 12 noon.
- How far had Vincent covered when he met Eric on the way?
- How far apart were the two parks?
(a)
Time taken by Eric = 6 h
Time taken by Vincent = 6 - 3 = 3 h
Distance covered by Vincent when he met Eric
= 3 x 70
= 210 km
(b)
Distance travelled by Eric
= 6 x 62
= 372 km
Distance of the two parks
= (210 + 372) ÷ 2
= 582 ÷ 2
= 291 km
Answer(s): (a) 210 km; (b) 291 km
