    Finding Acceleration Help

    At 10:15 AM, Snail 1 crossed the 65-cm mark with a velocity of 4 cm/min. In a great burst of energy. Snail 1 raced to the 90-cm mark in 3 minutes. His velocity as he crossed the 90-cm mark was 7 cm/min. What was the acceleration of snail 1?

    I got 1 cm/minute/sec

    Is this correct?

    recheck your units ...

    a = \frac{\Delta v}{\Delta t} = \frac{7 \, \frac{cm}{min} - 4 \, \frac{cm}{min}}{3 \, min}

    no conversion is necessary ...

    units for this problem are \frac{cm}{min^2}

    Yes it will since the problem didn't ask us to change it to a different unit.
