Latoya drove 693 miles in 11 hours. At the same rate, how long would it take her to drive 315?
mixas84 [53]

Answer:

At the same rate it would take her <u>5 hours</u> to drive 315 miles.

Step-by-step explanation:

Given:

Latoya drove 693 miles in 11 hours.

So, to find at the same rate how long it would take her to drive 315 miles.

Now, for getting the rate of driving we put the formula:

<em>Time = 11 hours.</em>

<em>Distance = 693 miles.</em>

Speed = \frac{distance}{time}

Speed = \frac{693}{11}

Speed= 63\ miles\ hour.

Now, to get the time for her to drive 315 miles at the same rate:

Time=distance\div speed

Time = 315\div 63

Time = 5\ hours.

Therefore, at the same rate it would take her <u>5 hours</u> to drive 315 miles.

Artemon [7]

Answer:

the answer is C

Step-by-step explanation:

DVD = $17.99

total bill

= magazine + book + DVD

= $4.99 + $12.99 + 17.99

tax 6%

amount of tax
