Multi-Step Unit Conversions

Same Process Y'all :)

Steps

Write starting value
Multiply by first conversion factor (same units must be diagonal to cancel)
Multiply by second conversion factor (same units must be diagonal to cancel)
Cancel Units
Multiply fractions across

Multiple Choice

I am converting 69 km/hr to mi/min.

Conversion Factors:
1mi = 1.6km

1hr = 60min

Fill in the missing units.

\frac{69km}{1hr}\cdot\frac{1?}{1.6?}\cdot\frac{1hr}{60\min}=\frac{69mi}{96\min}=\frac{.71mi}{1\min}

$\frac{1mi}{1.6km}$

$\frac{1.6km}{1mi}$

$\frac{60\min}{1hr}$

$\frac{1hr}{60\min}$

Multiple Choice

I am converting 69 km/hr to mi/min.

Conversion Factors:
1mi = 1.6km

1hr = 60min

Fill in the missing units.

\frac{69km}{1hr}\cdot\frac{1mi}{1.6km}\cdot\frac{1?}{60?}=\frac{69mi}{96\min}=\frac{.71mi}{1\min}

$\frac{1mi}{1.6km}$

$\frac{1.6km}{1mi}$

$\frac{60\min}{1hr}$

$\frac{1hr}{60\min}$

Steps

Write start value
Multiply by conversion factors. (Units must be diagonal to cancel out)
Cancel out units.
Multiply

Multiple Choice
