An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5
s
m
5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3
s
2
m
3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35

35, space, start fraction, m, divided by, s, end fraction leftward.
how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5
s
m
5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35
s

35, space, start fraction, m, divided by, s, end fraction?
answer using a coordinate system where rightward is positive.
must be a decimal
