Answer
a) $ 6 \frac{2}{3}m $
b) $ 100,000m $
c) $ 30m/s $
d) $ ≈ 0.2m $
Work Step by Step
Using data from the approximation table specified in the question, multiply each of the given units by the ratio between units.
a) $ 20ft \times \frac{1m}{3ft} ≈6 \frac{2}{3}m$
b) $ 60mi \times \frac{1km}{0.6mi} \times \frac{1000m}{1km} ≈ 100,000m$
c) $ 60mph \times \frac{1m/s}{2mph} ≈ 30m/s $
d) $ 8in \times \frac{10cm}{4in} \times \frac{1m}{100cm} ≈ 0.2m $
