Answer:
The number of once is 9.1
The number of hundreds is 8.9
Step-by-step explanation:
Given as :
The total of digits having ones and hundreds = 900
The sum of digits = 18
Let The number of ones digit = O
And The number of hundreds digit = H
So, According to question
H + O = 18 .........1
100 × H + 1 × O = 900 ........2
Solving the equation
( 100 × H - H ) + ( O - O ) = 900 - 18
Or, 99 H + 0 = 882
Or , 99 H = 882
∴ H = 
I.e H = 8.9
Put the value of H in eq 1
So, O = 18 - H
I.e O = 18 - 8.9
∴ O = 9.1
So, number of once = 9.1
number of hundreds = 8.9
Hence The number of once is 9.1 and The number of hundreds is 8.9

Answer:
Suzie walks faster by 0.27 miles per hour.
Step-by-step explanation:
Addie walked
miles in 45 minutes and Suzie covered
miles in
of an hour.
So, Addie walked 2.5 miles in 45 minutes i.e.
hours.
Therefore, the walking speed of Addie is
miles per hour.
Again, Suzie covered
i.e. 2.4 miles in
i.e. 0.67 hours.
So, the walking speed of Suzie is
miles per hour.
Hence, Suzie walks faster by (3.6 - 3.33) = 0.27 miles per hour. (Answer)
