Answer:
The second table.
Step-by-step explanation:
In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43. It decreases and then increases. This is not the correct table.
In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47. It increases and then decreases; this is the correct table.
To verify, we check the last two tables. The third table stays at 45, then decreases to 43 and 41. This is not correct.
The last table decreases from 45 to 43, then decreases to 41, then stays constant. This is not correct.
The second table is the only correct one.

Answer is Option B = 5/7
Explanation:
A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Kx, K is the scale factor for x. K is also the coefficient of x, and may be called the constant of proportionality of y to x.
For big pictures or maps, images should be drawn without affecting the shape in a small paper. Hence dimension of x is reduced to y with constant proporiton k which is scale factor
Here we find that original length of PC = 21
In image P'C = 15
Hence scale factor=15/21 = 5/7
Thaw answer is the b because
