Answer:

-7

Step-by-step explanation:

We can follow PEMDAS and see that first we do 4+2 which is 6.  Our equation looks like 5 - (6)2.  Since multiplication comes before subtraction we multiply 6 * 2 which is 12. Now we can fit that in 5 - 12 = -7

A horse runs 800 meters in 32.0 seconds.
goldenfox [79]

The average speed of the horse is 25.0m/s

<h3>What is speed?</h3>

Speed is the rate of change of distance over time

The given parameters are:

  • Distance (d) = 800 meters
  • Time (t) = 32.0 seconds

The average speed of the horse is then calculated as:

Speed = \frac{Distance}{Time}

This gives

Speed = \frac{800}{32.0}

Evaluate the quotient

Speed = 25.0

Hence, the average speed of the horse is 25.0m/s
