Question 12 Bryan wants to convert a speed of 85 kilometers per hour into the equivalent speed in meters per second Which expression shows the

Answer :

The conversion of 85 kilometer/hour to meter per second will be 85 × 1000/3600 meter/second so option (B) will be correct.

What is unit conversion?

To convert any unit into another called unit conversion.

In order to convert unit we need to care about their dimensions thier dimension should not be change.

For example conversion of kilometer to meter is to multiply by 1000 but meter and kilometere both unit is for distance only.

Another example could be kilo gram to gram.

Given,

85 kilometer /hour

Now,

Since 1 kilometer = 1000 meter

And

1 hour = 60 minutes

Since 1 minute = 60 seconds

So,

60 minutes = 60 × 60 seconds

1 hour = 3600 seconds.

Now,

⇒ 85 kilometer /hour

⇒ (85 × 1 kilometer )/(1 hour)

Since,

1 kilometer = 1000 meter

1 hour = 3600 seconds

So,

(85 × 1 kilometer )/(1 hour) = (85 × 1000 meter )/(3600 second)

Hence, The conversion of 85 kilometers/hour to meters per second will be 85 × 1000/3600 meters/second.

85 km/h x 1000m/1km x 1h/3600s

Option B is our answer.

Given,

Bryan wants to convert a speed of 85 kilometers per hour into the equivalent speed in meters per second.

We have to check which expression in the given option shows the correct representation.

How do we do the unit conversion?

When we convert from one unit to another unit either divide or multiply with the required values.

If we convert from a bigger unit to a smaller unit we multiply and if we convert from a smaller unit to a bigger unit we divide.

For example:

1 hour = 60 minutes

If we have to change hours to minutes we will multiply 60.

If we change from minutes to hours we will divide it by 60.

We have,

85 kilometers per hour

We can write it as,

85 kilometers = 1 hour

Converting kilometers into meters.

1 kilometers = 1000 meters.

Multiplying 85 on both sides.

85 x 1 kilometers = 85 x 1000 meters

85 kilometers = 85000 meters

Converting hours into seconds

1 hour = 60 minutes

1 minute = 60 seconds

1 hours = 60 x 60 seconds = 3600 seconds

85000 m/3600 s is our answer.

Thus 85 km/h x 1000m/1km x 1h/3600s is our answer.
