A road sign gives drivers information about traffic on busy highways. One sign shows 15 miles in 20 minutes. What is this speed

SIZIF [17.4K]

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.

$Speed=\frac{Distance}{Time}$

Now, we will put the value of distance and time in the above formula:

$Speed=\frac{15}{20}\times 60\\\\Speed=15\times 3\\\\Speed=45\ mph$

Hence, Speed in miles per hour is 45 mph.
