Well we need to follow PEMDAS. Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. The "X" is in the Exponents place. Therefore we would take 10 X 5.5 first. Which equals 55. Then you have to take it times 1. So the answer to the first one is 55. Then with the next one, you do the same steps, except at the end, your exponent is 2. So you would take 55 times 55 and get 3,025. So the answer to your second one is 3,025. Hope this is correct and hope this helps!

Answer:

4 hours and 30 minutes.

Step-by-step explanation:

660 miles = 1 hour
1320 miles = 2 hours
1980 miles = 3 hours
2640 miles = 4 hours

There are only 330 miles left and that is half of 660mph so therefore it would only take half an hour for these last 330 miles.

So we know that it will be taking 4 hours, you would then add the 30 minutes which gives you 4 hours and 30 minutes.

Hope this helps!
