NOTE: PLASES DO ALL THE STAPS

Answer 1

Answer: A=56 B=12 C=28 and D=24

Explanation:

A. Chad drove 168 miles in 3 hours

In 1 hour he drove 168÷3

= 56 Miles

B. We know,

Covering 56 miles takes 1 hour

So, It will take to cover 672 miles
= 672÷56

= 12 Hours

C. We know,

Chad drove 308 miles with 11 gallons of gas

So, miles per gallon chads car gave him 308÷11

= 28 Miles Per Gallon.

D. We know,

Chad car gives him 28 miles per gallon

So, To cover 672 miles

Chad needs = 672÷28

= 24 Gallons.

Answer 2

A: 24, B: 12, C: 28, D: 24. Hope this helps

Explanation:

Part A:

168/3 = 56

Therefore, Chad is driving the car in 56 mph.

672/56 = 12

Therefore, Chad drives 672 miles in 12 hours.

308/11 = 28

Therefore, Chad drives 28 miles per gallon of gas.

672/28 = 24

Therefore, Chad uses 24 gallons of gas to drive 672 miles.

Part B:

12 hours, you can use proportions, miles/hours.

`(56)/(1)`=
`(672)/(x)`

x = 12

Part C:

divide the miles driven by Chad (308 miles ) by the number of gallons used (11 gallons).

308 miles / 11 gallons =28 miles per gallon

Chad's car gets 28 miles per gallon.

Part D:

`(28)/(1) = (672)/(x) \\`

28x = 672

x = 672/28 = 24

24 gallons
