2. ignacio is going on vacation. he needs to drive 479 miles in 7 hours. what is his average speed in miles per
hour?
a. 71 miles per hour
c. 66 miles per hour
b. 64 miles per hour
d. 60 miles per hour

Step-by-step explanation:

Remember that

The speed is equal to divide the distance by the time

To find out the average speed or unit rate, divide the total distance by the total time

Let

x -----> the distance in miles

y ----> the time in hours

so

The average speed is x/y

substitute the values

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
