A road sign gives drivers information about traffic on busy highways. One sign shows 15 miles in 20 minutes. What is this speed
2 answers:
Answer: Speed in miles per hour is 45 mph.
Step-by-step explanation:
Since we have given that
Distance covered = 15 miles
Time taken to cover the above mentioned distance = 20 minutes
We need to calculate the speed in miles per hour ,
As we know the formula for " Speed " i.e.
Now, we will put the value of distance and time in the above formula:
Hence, Speed in miles per hour is 45 mph.

Here, we want to find the diagonal of the given solid
To do this, we need the appropriate triangle
Firstly, we need the diagonal of the base
To get this, we use Pythagoras' theorem for the base
The other measures are 6 mm and 8 mm
According ro Pythagoras' ; the square of the hypotenuse equals the sum of the squares of the two other sides
Let us have the diagonal as l
Mathematically;
Now, to get the diagonal, we use the triangle with height 5 mm and the base being the hypotenuse we calculated above
Thus, we calculate this using the Pytthagoras' theorem as follows;
