1. In 2 hours a jet flew 975 miles. What was
the jet's average speed?

487.5 miles per hour

Step-by-step explanation:

to find average simply divide 975÷2

C. x 0

Step-by-step explanation:

The answer is C, x is greater than or equal to zero, because that is the only answer that makes sense.

A) x can also be equal to 0, so this answer is wrong

B) x can't be -2, and it definitely can't be less than -2, so that's wrong.

D) Again, x can't be -2, or -1. It can't be any negative number because 4 * (a negative number) would put a negative sign under the square root. You can't take square roots of negative numbers.

Hope this is correct and that it helps you!
