No it can not if you don't understand why ask why
Her grandma will be there 40 minutes early. If you add the hours first, then it makes it 6:35. Add the 50 minutes, 7:25 is the arrival time.
D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
I think 115 min because its just 23 x 5 so you just multiply that to get the asnwer
