Question

The speed of a train is 120 km per hour it is increased by 10% find the increase in the speed also find its new speed

Answer 1

Answer:

Step-by-step explanation:

The speed of the train is 120 km

To find the increase we have to find the value of 10% of 120 i.e(that is)

10% of 120 =120/100*10

which will give you

12.

So the increase in speed is 12km and the new speed is 132 km

Answer 2

Given:

The speed of a train is 120 km/h it is increased by 10%.

To Find:

Find the increase in the speed also find its new speed?

Step-by-step explanation:

• Speed can be defined as the rate at which someone or something can be moved.
• The speed of the train is 120km per hour and it is increased by 10 percent.

• Now, we will find ten percent of 120.

        $\textrm{10 percent of 120}=\frac{120}{10} \times 100$

                                    $=12$

It means the speed of train is increased by 12 km per hour.

• The new speed of the train is equal to the sum of the running speed of the train and the increased speed.

        $\textrm{ New speed of train}=120+12 =132 km/h$

New speed of the train is 132 km/h.
