At 9 a.m., Tommy and Warren left Park H and drove towards Park J at average speeds of 95 km/h and 60 km/h respectively. Upon reaching Park J, Tommy rested for 3 hours. He then headed back for Park H at an average speed of 95 km/h along the same route. Tommy and Warren met each other on their way at 2 p.m.
- How far had Tommy covered when he met Warren on the way?
- How far apart were the two parks?
(a)
Time taken by Warren = 5 h
Time taken by Tommy = 5 - 3 = 2 h
Distance covered by Tommy when he met Warren
= 2 x 95
= 190 km
(b)
Distance travelled by Warren
= 5 x 60
= 300 km
Distance of the two parks
= (190 + 300) ÷ 2
= 490 ÷ 2
= 245 km
Answer(s): (a) 190 km; (b) 245 km
