Answer:

The speed is equal to 5\frac{mi}{h}

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x------> the distance in miles

y-----> the time in hours

s----> the speed in mph

so

s=\frac{x}{y}

In this problem we have

x=(1/4)\ mi

y=(1/20)\ h

substitute

s=\frac{(1/4)}{(1/20)}=20/4=5\frac{mi}{h}

If the hypothesis is false, an argument cannot be valid, how would you explain this?
Elodia [21]
If the hypothesis was wrong, all you simply have to do is state the hypothesis was wrong and why you think it was, and add what you can do to change it or to make it better so next time it will be right. Just state what you did and how you got your answer.

I hope that helps!

A cube has a volume of greater than 123 cm3. What are the possible lengths of the side of that cube?
horrorfan [7]
When we cube root 123, we get a decimal which rounds out to 4.97. So possible side lengths would be any number greater than that.<span />
