What is multiplication?
When a quantity is added many times then the process is called multiplication. For example if 2 is added 10 times then the result will be 20. In terms of multiplication it can be written as 2 X 10 = 20.
After the first hour fuel in the plane is 150,000 pounds. Hence, calculate the amount of fuel consumed in 9 hr to find the remaining fuel after the tenth hr.
The four engines consume a total of 12,000 in one hr. Hence, total fuel consumed in 9 hr = (Fuel consumed in one hr)(Total hr)
= (12000 Pounds)(9 hr)
= 108,000 Pounds
Now, fuel remaining after the tenth hr = 150,000 - 108,000
= 42,000 Pounds
Hence, the fuel remaining after the tenth hr is 42,000 Pounds. It can be solved by multiplication and subtraction techniques.
