Express the following relationship as a rate. 310 miles in 5 hours a. 60 miles per hour b. 62 miles per hour c. 58 miles per hour d. 64 miles per hour

Hi!

We know that the relationship is 310 miles in 5 hours.

310 miles in 5 hours

x miles per  1 hour

x = (310*1)/5

x = 310/5

x = 62

The correct answer is B. 62 miles per hour

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
