Ely walks 7/8 mile in 1/3 hour. what is his speed miles per hour?

The value of x is:

                     32.

It is given that:

The hypotenuse of a right angled triangle is lav=belled as: x

Also, one of the angle of the right triangle is 30° such that the side opposite to this angle is of length 16 units.

Now, we will use the sine trignometric ratio as:

Hence, the hypotenuse of the right angled triangle is: 32 units.
