It's answer a y=x^2
multiple each number twice
4•4 16
2•2 4
3•3 9
3:30 because 105/60 equals 2.15
then you just add the time to the starting time
If it is a rhombus then you know each side is the same length, so only have to work out one side. To do this you have to use Pythagoras' theorem (a^2 + b^2 = c^2)
So take two sets of coordinates, for example, (0,3) and (5,3), a and b represent the height difference and the length difference. Therefore (5-0)^2 + (3-3)^2 = c^2
c^2 = 25
c = 5 , which would be the side of the rhombus
1hr = 60minutes
60min + 45 min = 105
4545÷105 = 47,7225 miles
