At 5 a.m., Tommy and Oliver left Park W and drove towards Park X at average speeds of 91 km/h and 59 km/h respectively. Upon reaching Park X, Tommy rested for 2 hours. He then headed back for Park W at an average speed of 91 km/h along the same route. Tommy and Oliver met each other on their way at 1 p.m.
- How far had Tommy covered when he met Oliver on the way?
- How far apart were the two parks?
(a)
Time taken by Oliver = 8 h
Time taken by Tommy = 8 - 2 = 6 h
Distance covered by Tommy when he met Oliver
= 6 x 91
= 546 km
(b)
Distance travelled by Oliver
= 8 x 59
= 472 km
Distance of the two parks
= (546 + 472) ÷ 2
= 1018 ÷ 2
= 509 km
Answer(s): (a) 546 km; (b) 509 km
