when writing scientific notation, there must be one number to the left of the decimal point.
To achieve this in this problem, you need to move the decimal point 3 times to the right.
because you are moving the point to the right, the exponent will be negative.
*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*
therefore you answer should be written as:

1c = 16t = x(

)
1c = 16t = 16 X 3
1c = 16t = 48

If I am correct the answer is 369,600 feet per hour.
60 = (10 + 20 + 30 + 40 + x)/5
300 = 100 + x
x = 200
