At 7 a.m., George and Tim left Park K and drove towards Park L at average speeds of 90 km/h and 62 km/h respectively. Upon reaching Park L, George rested for 3 hours. He then headed back for Park K at an average speed of 90 km/h along the same route. George and Tim met each other on their way at 1 p.m.
- How far had George covered when he met Tim on the way?
- How far apart were the two parks?
(a)
Time taken by Tim = 6 h
Time taken by George = 6 - 3 = 3 h
Distance covered by George when he met Tim
= 3 x 90
= 270 km
(b)
Distance travelled by Tim
= 6 x 62
= 372 km
Distance of the two parks
= (270 + 372) ÷ 2
= 642 ÷ 2
= 321 km
Answer(s): (a) 270 km; (b) 321 km
