At 7 a.m., Vincent and Reggie left Park G and drove towards Park H at average speeds of 75 km/h and 58 km/h respectively. Upon reaching Park H, Vincent rested for 3 hours. He then headed back for Park G at an average speed of 75 km/h along the same route. Vincent and Reggie met each other on their way at 2 p.m.
- How far had Vincent covered when he met Reggie on the way?
- How far apart were the two parks?
(a)
Time taken by Reggie = 7 h
Time taken by Vincent = 7 - 3 = 4 h
Distance covered by Vincent when he met Reggie
= 4 x 75
= 300 km
(b)
Distance travelled by Reggie
= 7 x 58
= 406 km
Distance of the two parks
= (300 + 406) ÷ 2
= 706 ÷ 2
= 353 km
Answer(s): (a) 300 km; (b) 353 km
