Novosadov [1.4K]

Answer:

1.5 per hour : 1.2 per hour

Step-by-step explanation:

The computation of the ratio is shown below:

For norma, the one pool would be

= 12 pools ÷ 8 hours

= 1.5 per hour

And for albert, the one pool would be

= 9 pools ÷ 7.5 hours

= 1.2 per hour

So the ratio between them is

1.5 per hour : 1.2 per hour

Noah loves the Half-Tens facts and often uses them to solve multiplication problems. Make up a 2-digit by 3-digit multiplication

Stells [14]

Half Tens is a way of multiplying where we have to find the value of given numbers. First we double any 'one' of the two given numbers and multiply both to get an answer. Then we divide that answer by '2' to get the answer.

Lets take two numbers as 16 and 340

$16\times340=?$

Double the number 16

$32\times340=10880$

Now we will divide this by 2

$\frac{10880}{2}= 5440$

So, if we check $16\times340=?$ , it is 5440.

Similarly if we double the number 340, we get 680

Now, $16\times680=10880$

And 10880/2 = 5440

Hence, in both ways the answer is 5440.

A train 100 m long crosses a pole in 5 seconds.Find the speed of the train in kilometre per hour.

In-s [12.5K]

Answer:

$\sf72 km/h$

Step-by-step explanation:

Distance covered by the train in crossing the pole = 100 m.

$\sf Time \: taken=5 \: seconds$

$\sf \: Speed \: of \: the \: train = \frac{Distance }{Time}$

$\sf = \frac{100}{5} \: m/s$

$\sf \: = 20 \: m/s$

$\sf \: = 20 \times \frac{18}{5} \: km/h$

$\sf = 72 \: km/h$

Hence, the speed of the train is 72 km/h
