Answer:
1 hour and 15 minutes
Step-by-step explanation:
Nuala drives 20 miles per hour, which makes the trip 2 hours and 30 minutes long. If Nuala drove at 40 miles per hour, the trip would take 1 hour and 15 minutes. Why? Because:
40 miles per hour
50 miles- 40 miles=10 miles (that makes 1 hour already)
so now we figure out how long it takes for 10 miles at the speed of 40 miles per hour.
10/40=1/4 and 1/4 of an hour or 60 minutes is 15 minutes.
Therefore, it would take Nuala 1 hour and 15 minutes if she drove 40 miles per hour.
Hope this helped!

Answer: 8.67 x 
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point. In this problem, we can write 8,670,000,000 as 8.670000000. Notice that there is only one digit to the left of the decimal point. Next, we count the number of places the decimal point would need to move to get back to our starting number which is 8,670,000,000. In this case, the decimal point would need to move 9 places to the right in order to get back to our original number. This would make our exponent positive 9 because we would need to move to the right 9 places. Lastly, we can drop any zeroes that are at the end of the decimal. Therefore, 8,670,000,000can be written in scientific notation as 8.67 x
