At 6 a.m., Warren and Vincent left Park S and drove towards Park T at average speeds of 97 km/h and 50 km/h respectively. Upon reaching Park T, Warren rested for 3 hours. He then headed back for Park S at an average speed of 97 km/h along the same route. Warren and Vincent met each other on their way at 1 p.m.
- How far had Warren covered when he met Vincent on the way?
- How far apart were the two parks?
(a)
Time taken by Vincent = 7 h
Time taken by Warren = 7 - 3 = 4 h
Distance covered by Warren when he met Vincent
= 4 x 97
= 388 km
(b)
Distance travelled by Vincent
= 7 x 50
= 350 km
Distance of the two parks
= (388 + 350) ÷ 2
= 738 ÷ 2
= 369 km
Answer(s): (a) 388 km; (b) 369 km
