Question

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.

Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at
590 mph.
Which equation is correctly written in standard form to represent this scenario?
0 590a - 550b = 1275
550a +590b = 1275
590a + 550b = 1275
550a - 5906 = 1275

Answer 1

550a + 590b = 1275

Explanation:

We use the following relation to solve this question:

`v = (d)/(t)`

In which v is the velocity, d is the distance and t is the speed.

In this question, we find the distance, so we use:

`d = v*t`

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.

This means that
`d = 1275`.

Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.

This means that
`v*t = 550a + 590b`.

Which equation is correctly written in standard form to represent this scenario?

`d = v*t`

1275 = 550a + 590b

550a + 590b = 1275
