Question

A car moves with a constant speed of 220 km/h. Express this speed in m/s and calculate the distance covered in 20 seconds​

Answer 1

Formula:

• D = v • t
• Resolver:
• D = (61.1m/s) • (20s)
• D = 1222m

Hope this helped

Answer 2

Hello..!

We first apply the data to the problem.

Data:

• V = 220km/h
• T = 20s
• D = ?

Now, we convert the "km/h" to "m/s".

Conversion:

• 220km/h • (1000m/1km) • (1h/3600s)
• V = 61.1m/s

Then, we apply the formula that is.

Formula:

• D = V • T

Finally we develop the problem.

Developing:

• D = (61.1m/s) • (20s)
• D = 1222m

The distance covered is 1222 meters.
