The answer is x= +- 2 square root of 2 + 3
Using the speed - distance relationship, the distance traveled by Joanne would be 55.714 km
Kuzi's speed :
- <em>16</em><em>/</em><em>2</em><em> </em><em>=</em><em> </em><em>8km</em><em> </em><em>/</em><em> </em><em>hr</em><em> </em>
Joanne's speed :
- <em>6km</em><em>/</em><em>hr</em><em> </em>
Let time taken = <em>t</em>
<u>Total</u><u> </u><u>distance</u><u> </u><u>traveled</u><u> </u><u>:</u>
8t + 6t = 130
14t = 130
t = 130/14
t = 9.2857142 hours
<u>Therefore, distance traveled by Joanne</u> :
Joanne's speed × time
6 km × 9.2857142 = 55.714 km
Therefore, distance traveled by Joanne will be 55.714 km
