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.

All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit. 1/4 of the pupils come from E
Jlenok [28]

Answer:

<em>680</em>

Step-by-step explanation:

Given that:

All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit.

\frac{1}{4} of the pupils come from Elmswell

\frac{3}{5} of the pupils come from Haughley

102 pupils come from Woolpit.

To find:

Total number of pupils in the school.

Solution:

Let total number of pupils = 100x

So, number of pupils that come from Elmswell = \frac{1}{4} of 100x

OR

\dfrac{1}{4} \times 100x\\\Rightarrow 25x

And, number of pupils that come from Haughley= \frac{3}{5} of 100x

OR

\dfrac{3}{5} \times 100x\\\Rightarrow 60x

Number of pupils that come from Woolpit = 100x - 25x - 60x \Rightarrow 15x

As per given statement:

15x = 102\\\Rightarrow x =6.8

Number of pupils from Elmswell = 25x = 25 \times 6.8 = 170

Number of pupils from Haughley = 60x = 60 \times 6.8 = 408

Total number of pupils at the school = 100x \Rightarrow 100 \times 6.8=680
