If it takes a sloth 10 minutes to climb 7.5 feet what’s its climbing speed in miles per hour
qwelly [4]

Answer:

.009  miles/hour

Step-by-step explanation:

\frac{7.5}{10}\frac{feet}{minutes} * \frac{1}{5280}   \frac{miles}{feet} *\frac{60}{1}\frac{minutes}{hour}

This is the method you should take with unit conversions in general, just set up fractions so the units cancel out, like the 7.5 feet cancels out with the feet in the 1/5280 so miles is left on top.
