Answer:
<em>The answer is 13</em>
Step-by-step explanation:
Two positive and consecutive old numbers are x and x - 2.
=> x(x - 2) = 143
=> x^2 - 2x - 143 = 0
=> x^2 + 11x - 13x - 143 = 0
=> x(x + 11) - 13(x + 11) = 0
=> (x + 11)(x - 13) = 0
=> x = -11 (invalid)
or x = 13 (valid), the remaining number is 13 - 2 = 11
=> The two numbers are 11 and 13, and the greater number is 13.

The total length was 6 m.
One of the tables was 1.8 m
Subtract 1.8 from 6 to find the total length of the other two tables:
6 - 1.8 = 4.2m
The other two tables are the same size, so now divide 4.2 m by 2:
4.2 / 2 = 2.1
The other tables are 2.1 m long.
1614 divided by 4 is 403.5
The answer is 9.3, divide the distance between town A&B by the speed of the automobile. 420/45= 9.3 hours.
