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:

550a + 590b = 1275

Step-by-step explanation:

We use the following relation to solve this question:

[tex]v = \frac{d}{t}[/tex]

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:

[tex]d = v*t[/tex]

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

This means that [tex]d = 1275[/tex].

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 [tex]v*t = 550a + 590b[/tex].

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

[tex]d = v*t[/tex]

1275 = 550a + 590b

550a + 590b = 1275
