First part of the question is 400 miles per hour
No. The two units are not comparable. Miles per hour is a speed. Knots per hour is an acceleration. However, I think the question was wrongly phrased and by knots per hour the question actually meant just knots (nautical miles per hour.) A nautical mile is longer than a mile: 1 nautical mile = ~1.15 miles. So 19 knots = 1.15 * 19 miles per hour = 21.85 mph. The answer is: Yes (if by knots/hr the question really meant knots) or No (if the question was initially correctly phrased.)
You must make a formula and convert the units to solve this problem. 65 miles per hour is a speed. 850 miles is a length. If you are travelling at 65 miles per hour, then you will have traveled 65 for every hour. At this point, it becomes a simple division problem. 850 miles covered at 65 miles per hour is 850 miles/65 miles/hour. 850/65 = ~13. The miles on the top and bottom of the fraction cancel out, and you are left with hours. So the time taken will be ~13 hours.
Assuming the question is refering to feet PER second and miles PER hour, 176 fps = 120 mph
1 km is a measure of distance, not speed. On the other hand, miles per hour is a measure of speed not distance. So there is a basic fault in the question.1 km = 0.621 milesand 1 km PER HOUR = 0.621 miles per hour
If this is a yes or no question, then the answer is yes.
the answer for this question is 35 miles. Answer given in question itself. In this question it stated speed as 35 miles per an hour. That means 35 miles can be driven in an hour with the speed of 35mph.
This question cannot be answered in its current form. Miles per kilometer is not possible as both miles and kilometers are both distance units. In order to measure speed you must have both a distance unit and a time unit. If the question was meant to be "How fast is 500 kilometers per hour in miles per hour?" then the answer is 310.685596 miles per hour as there is 0.621371192 miles per kilometer or 1.609344 kilometer per mile. Likewise, if you're looking for "How fast is 500 miles per hour in kilometers?" then you will arrive at 804.672 kilometers per hour.

Megahertz is a measure of frequency while miles per hour is a measure of speed. It is impossible to answer your question.

Er .... I'm not sure you have thought about this question. If you are traveling 80 miles per hour, you go 80 miles in one hour. That is the definition of "miles per hour."
You must make a formula and convert the units to solve this problem. 65 miles per hour is a speed. 850 miles is a length. If you are travelling at 65 miles per hour, then you will have traveled 65 for every hour. At this point, it becomes a simple division problem. 850 miles covered at 65 miles per hour is 850 miles/65 miles/hour. 850/65 = ~13. The miles on the top and bottom of the fraction cancel out, and you are left with hours. So the time taken will be ~13 hours.
Miles per hour is a measure of speed, your question asks for an amount of time (I think).

50 miles per hour.
1 km is a measure of distance, not speed. On the other hand, miles per hour is a measure of speed not distance. So there is a basic fault in the question.1 km = 0.621 milesand 1 km PER HOUR = 0.621 miles per hour
