At 6 a.m., Tommy and Zane left Park N and drove towards Park P at average speeds of 90 km/h and 58 km/h respectively. Upon reaching Park P, Tommy rested for 2 hours. He then headed back for Park N at an average speed of 90 km/h along the same route. Tommy and Zane met each other on their way at 12 noon.
- How far had Tommy covered when he met Zane on the way?
- How far apart were the two parks?
(a)
Time taken by Zane = 6 h
Time taken by Tommy = 6 - 2 = 4 h
Distance covered by Tommy when he met Zane
= 4 x 90
= 360 km
(b)
Distance travelled by Zane
= 6 x 58
= 348 km
Distance of the two parks
= (360 + 348) ÷ 2
= 708 ÷ 2
= 354 km
Answer(s): (a) 360 km; (b) 354 km
