which expression is the unit rate for 36m/4sec. A)2m/1sec. B)9m/1sec. C)10/1sec. D)36m/1sec

Cross multiply and solve for x.

36/4 = x/1

i don't understand please be more understanding

Cross multiply and solve for x.

36/4 = x/1

4x = 36

x = 36/4

x = 9

9 meters per second

To find the unit rate for 36m/4sec, we need to determine how much meters are covered in one second.

Divide the given distance, 36m, by the given time, 4sec:

36m/4sec = 9m/sec

So, the unit rate for 36m/4sec is 9m/1sec.

Therefore, the correct answer is (B) 9m/1sec.
