What units in the metric system would you use to measure each of the following
quantities?=
The United States emitted 19.5 million t of nitrogen oxides
(NO) into the atmosphere in 1987. One metric ton (1 t) equals 1,000 kg. How many
kilograms of NO were emitted to the atmosphere in the United States during 1987?=19,500,000,000
Complete each statement. (Round to the nearest hundredth.)72 in. =182.88 cm
7 L = 7.35 qt
Samantha’s speedometer reads in kilometers per hour. If
the legal speed limit is 55 mi/h, how fast can she drive?88.5 km per hr

88.5 km/hr is correct.
I get 7.396 qts which would round to 7.40.
182.88 cm is correct.
I don't understand the question for the first one.
