Let x represent the number.
.. x^2 +x = 2
.. x^2 +x +1/4 = 9/4 . . . . add 1/4 to complete the square

Numbers meeting that requirement are -2 and 1.
<span>Find the round trip distance:
4.95 km/hr * 48 min * 1 hr/60 min = 3.96 km
1.98 km each way
d = r*t
t = d/r = 1.98/4.5
t = 0.44 hrs upstream
t = 26.4 minutes upstream</span>
