a) 3.05km
b) 30.5km
c) 1.89km
d) 18.9km
1000m
d) 0.4m

Answer 1

a

Step-by-step explanation:

10,000ft/1×1mi/5280ft×1.61km/mi=3.05km

Cross out the units with the target unit on the top. ft in the numerator cancels out with ft in the denominator, then mi in numerator cancels out with mi in denominator leaving km, your target.

Answer 2

Below

Step-by-step explanation:

10 000 ft / 5280 ft/mi * 1.61 km/ mi = 3.05 km

(see how the 'ft' and 'mi' cancel out and you are left with km??)
