At 5 a.m., Tommy and Nick left Park L and drove towards Park M at average speeds of 96 km/h and 60 km/h respectively. Upon reaching Park M, Tommy rested for 2 hours. He then headed back for Park L at an average speed of 96 km/h along the same route. Tommy and Nick met each other on their way at 1 p.m.
- How far had Tommy covered when he met Nick on the way?
- How far apart were the two parks?
(a)
Time taken by Nick = 8 h
Time taken by Tommy = 8 - 2 = 6 h
Distance covered by Tommy when he met Nick
= 6 x 96
= 576 km
(b)
Distance travelled by Nick
= 8 x 60
= 480 km
Distance of the two parks
= (576 + 480) ÷ 2
= 1056 ÷ 2
= 528 km
Answer(s): (a) 576 km; (b) 528 km
