Answer:
Option B.
Step-by-step explanation:
A bicyclist rides the same number of miles in one minute.
Ratio table is given as
Number of minutes Distances (miles)
10 2.5
16 4
x 7.5
48 12
We have to find the number of minutes taken by a biker to bike 7.5 miles
So the ratio between minutes to the distance biked will be =
Now this ratio will be similar to the ratio =
Now
x = 7.5×4 = 30 minutes
Therefore, Option B will be the answer.

Angles RLN and MLK would be vertical angles.
Right. Vertical angles are formed when their sides share the same lines. RL shares the same line with LM and NL shares the same line with LK (see the attached diagram), so that means both angles form a vertical pair.
Angles RLN and MLN would be vertical angles.
Wrong. They are linear pairs, because they are adjacent and supplementary. Adjacent angles share a side – in this case, LN. Supplementary angles sum 180°, which you can see is right because the other sides (ML and RL) are in the same line. RLN and MLN sum the same as the size of RLM, which is a line, so it’s 180°. <span>
Angles RLN and KLM would be a linear pair. </span>
Wrong. They would be a vertical pair (see definition of vertical pair in the first option). RL is opposed to LM and LN is opposed to KL.
Angles RLN and KLN would be a linear pair.
Wrong. KLN is actually a line, so it’s actually 180°, so it can’t be a linear pair with KLN. Linear pairs sum 180°, which is impossible because KLN itself is already 180°, so any sum will throw a higher number.
