ANSWER:
We know that,
Speed = Distance/Time
So, Time taken = 20kmh-¹/160km
64/3274=0.019547954
Hope this helps.
So you have to find something that multiples to six but also somehow either subtracts or adds to five. So I would pick 2 and 3 because two plus three is five. Then you would write out your equation
X2+2x+5x+6
This may not be the way your teacher taught however it is much easier for me to do it this way.
replace the numbers given for x & y so
the equation becomes 3*(-3) + 2*(-4) =
3*-3 = -9
2*-4 = -8
-9 + -8 = -17
How far are you rowing?
If your rowing speed is 1.5 times faster your going about 16 miles up to 2 hours in the river
