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.
