The unit rate is 6.4 yards per second.
Step-by-step explanation:
Given statement is;
400 yards in 62.5 seconds
As we have to find unit rate in terms of seconds; therefore, we will divide total yards by total seconds.
62.5 seconds = 400 yards
Dividing both sides by 62.5

The unit rate is 6.4 yards per second.

Recall your SOH CAH TOA, or

now, bear in mind that, the opposite side, to an angle, is the side right "in front of it", that is, if you were to put your eye on that angle, "the wall" you'd see on the other end, is the opposite side
the adjacent side, adjacent = next to, is the side that's touching the angle itself
and the hypotenuse, is always the slanted and longest side of all three
for example on 16, tangent of Z
if you put one eye on Z, you'll see on the other end, the side of 30 units
the adjacent side is the one touching Z, or the 40 units side

and you'd do all others, the same way, using those ratios
