Question

Write a direct variation equation to find the number of miles a jet travels in 3 hours if it is flying at a rate of 600 mph.(1 point)
Responses

3=600x
3 equals 600 x

600=3x
600 equals 3 x

y=600×3
y equals 600 times 3

y=6003

1 answer

To find the number of miles a jet travels in 3 hours at a rate of 600 mph, we can use the direct variation equation of the form \( y = kx \), where \( k \) is the rate of travel (in this case, 600 mph), and \( x \) is the time in hours.

In this scenario:

  • \( k = 600 , \text{mph} \)
  • \( x = 3 , \text{hours} \)

Thus, we can write the equation as:

\( y = 600 \times x \)

Substituting for \( x = 3 \):

\( y = 600 \times 3 \)

So the correct response for the direct variation equation that describes this situation is:

y = 600 × 3
(y equals 600 times 3)
