How do you express 400 yards in 53 seconds as a unit rate?

just divide 400 by 53 and it becomes yards per second

Cross multiply and solve for x.

400/53 = x/1

53x = 400

x = 400/53

x = 7.55 yards per second

To express 400 yards in 53 seconds as a unit rate, you need to divide the distance (400 yards) by the time (53 seconds). This will give you the rate of how many yards are covered in one second.

So, the unit rate can be calculated as:

Unit Rate = Distance / Time

Unit Rate = 400 yards / 53 seconds

To simplify this fraction, you can divide the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 400 and 53 is 1, so dividing by 1 does not change the value.

Unit Rate = 400 yards / 53 seconds

Therefore, the unit rate for covering 400 yards in 53 seconds is approximately 7.55 yards per second.
