    [SOLVED] distance travelled- integration

    How's the best way to approach this using integrals some way or the other? I am confused...

    A rocket takes off in a path described by the equation y= \frac{2}{3}(x^2 - 1)^\frac{3}{2}. Find the distance travelled by the rocket (rounded to the nearest km) for x= 4.6 km, to x= 6.7km

    Would the distance traveled by the rocket be the length of the curve from x=4.6 to x=6.7?
