Iwill give brainl pls two planes left the same airport traveling in opposite directions. the first plane left at 9: 00 a. m. and 2.25 hours later, the two planes were 1825 miles apart. the second plane left at 10: 00 a. m. and its average rate was 108 miles per hour slower than the first plane's average rate. let x represent the first plane's average rate. what was the first plane's average rate? enter an equation that can be used to solve this problem in the first box. solve for x and enter the first plane's average rate in the second box. what is the equation and what is the

The Average rate of the first plane is 560 mph

Step-by-step explanation:

x = first plane's average rate (in mph)

x−108 = second plane's average rate (in mph)

First planes total distance = 2.25x

Second planes total distance = 1.25(x−108)

2.25x + 1.25(x−108) = 1825

x = 560

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
