Answer
a) $15.7 in$
b) $91.2 ft$
c) $6.21 miles$
d) $8477 lb$
Work Step by Step
a) To convert cm to in, divide by 2.54 because 1 in= 2.54 cm. $40.0 cm×\frac{1 in}{2.54 cm}=15.7 in$
b) To convert from m to ft, multiply by 3.281 because 1 m= 3.281 ft . $27.8 m×\frac{1 m}{1.094 yd}=91.2 ft$
c) To convert from km to miles, divide by 1.609 because 1 mi= 1.609 km
$10.0 km×\frac{1 mi}{1.609 km}= 6.21 mi$
d) To convert kg to lb, multiply by 2.205 because 1 kg= 2.205 lb. $3845 kg×\frac{2.205 lb}{1 kg}=8477 lb$
