Question

A plane is flying at a steady speed of 30000m/minute.

Answer 1

Answer:

4 seconds

Step-by-step explanation:

$\frac{30,000}{1} =\frac{2,000}x}$

The numerator is the distance and the denominator is the time.

I used cross multiplication, the numerator of one fraction times the denominator of the other.

$30,000*x=2,000*1\\30,000x=2,000$

divide both sides by 30,000 and simplify

$x=\frac{2,000}{30,000} \\x=\frac{2}{30}$

Then multiply the fractions by 2/2 (basically multiplying the numerator and the denominator each by 2)

$x=\frac{4}{60}$

Since the denominator is 60, the number of seconds in a minute, the numerator is the answer

I hope this makes sense ;-;
