At 6 a.m., Jack and Flynn left Park T and drove towards Park U at average speeds of 97 km/h and 59 km/h respectively. Upon reaching Park U, Jack rested for 2 hours. He then headed back for Park T at an average speed of 97 km/h along the same route. Jack and Flynn met each other on their way at 2 p.m.
- How far had Jack covered when he met Flynn on the way?
- How far apart were the two parks?
(a)
Time taken by Flynn = 8 h
Time taken by Jack = 8 - 2 = 6 h
Distance covered by Jack when he met Flynn
= 6 x 97
= 582 km
(b)
Distance travelled by Flynn
= 8 x 59
= 472 km
Distance of the two parks
= (582 + 472) ÷ 2
= 1054 ÷ 2
= 527 km
Answer(s): (a) 582 km; (b) 527 km
