Yes I believe it will.
miles ∝ hours
miles = k hours
where k = 1/72
1miles = 1/72 hours

This is a direct relationship.
Is this a good enough explanation?

Someone else might add something.

How do I calculate average speed miles per hour with 1 and a half hour

let's say you go D miles in 1 1/2 hrs.

1 1/2 = 3/2

so the average is D/(3/2) = 2D/3

so if you went say 120 miles in 1 1/2 hrs your average is 2*120/3 = 80 mph

I can't help you with your question but I can hlep with your presentation.

I am trying really hard to get people to use the 'sup' button which is located just above the smilies.
It makes it much easier to read your questions and answers. It also cuts down on misinterpretation of your questions.
If you want to enter x^2, it is better written as x ².
To do this you enter x then you hit the 'sup' button, the curser will automatically move to where you need to enter 2.
Once the 2 is there just move your curser to the end and keep going. It is quite quick when you get used to it.

The sub button is very similar.

I will put out a lantern to attract people to your question.

This is a children's forum (in part) and your language is not appreciated.

You are welcome here but the word that you have used is not.

okay,
Take your shoes and socks off.
You most likely have ten toes.
Divide them into 2 bundles. That is easy because you probably have 2 feet.
Now, how many toes are in each bundle? That is your answer.,

See. Maths is fun!

antilog of -0.43

Thank you again Dms,
btw Your picture is not displaying.

Hi Toshi,

log ₁₀ x = -0.43

10^( log ₁₀ x ) = 10 ^-0.43

x = 10 ^-0.43

10^-0.43
