I won't answer straight up, but here are clues to help you out.
Clues for question 1:
Unit measurements in the metric systems include:
millimeter (1/1000 of a meter) or about the thickness of a pen-tip
centimeter (1/100 of a meter) or about the length of a snail
meter is about the length from the floor to the doorknob
kilometer (1000 meters) or the length of multiple football fields.
Clues for question 2:
If one ton (1t) equals 1000 kilograms (kg) then two tons must equal 2000 kg and three tons equal to 3000 kg.
Ten tons == 10* 1000 kg == 10,000 kg.
One hundred tons == 100 * 1000 kg == 100,000 kg
One thousand tons == 1000 * 1000 kg
Ten thousand tons == 10,000 * 1000 kg
One million tons == ? * 1000 kg == ??
Clues for 3:
1 mile == 1.6093 kilometers
10 miles == 10 * 1.6093 kilometers == 16.093 km
20 miles == 20 * 1.6093 km == ?
55 miles == 55 * 1.6093 km == ??
55 miles per hour == your answer above in km / hour

[a] KILOMETERS
[b]Centimeters
[c]Micrometers.
[d]Centimeters.
The quantity of Nitrogen Oxide emitted in 1987 =19.50*1000=19500 million kilograms .
55miles per hour=55*1.6=88 kilometers per hour.
Samantha can drive up to 88 kilometers per hour

Mr Know-it-all got the speed wrong. 55 mph is 88.51 kph. Driving an old car it still has both miles and kilometres and 50 mph is 80 kph.
