8
hours to drive to the sales conference, what is his average speed in miles per hour?



60.44 miles per hour

Step-by-step explanation:

Distance (D) = 68miles

Time (T) = 1 1/8 hours Convert to Improper fraction

Time (T) = 9/8 hours

Speed (S) = ?

Average speed (S) = Total distance (D) / Time (T)

S = D/T

S = 68 / (9/8)

S = 68 ÷ 9/8

S = 68 * 8/9

S = 544/9

S = 60 4/9 miles per hour (in fraction)

S = 60.44 miles per hour (approximated to 2 decimal places)

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
