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?

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

would the units be cm/sec/sec?

the unit is meter by second squared...you have to convert all those values

no conversion is necessary ...

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

but it won't give the same answer as if it was converted

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