Answer:

The average speed is:

\var{v}=75\: miles/h

Step-by-step explanation:

The average speed equation is given by:

\var{v}=\frac{\Delta x}{\Delta t}

Were:

  • Δx is the displacement (225 miles)
  • Δt is the change in time (3 hours)

Then we have:

\var{v}=\frac{225}{3}

\var{v}=75\: miles/h

I hope it helps you!

Find the probalitywhen a pair of 8-sided fair die is rolled and the sum of the roll is greater than 9
Tresset [83]

Odd Numbers : 1, 3, 5, 7 = 4 numbers

Total numbers on 8-sided die = 8

P(rolling an odd number) = 4/8 = 1/2

Die is defined as ceasing to live, exist, or disappear. An example of this is pulling a plant out of the ground by its roots. An example of death is when a person's heart stops and the brain stops working. stop living; dead out.

Use ``die of'' when someone dies of direct causes. We use ``die of'' when someone died from an indirect cause. "die by" is used when someone dies from something. He died of cancer.
