Short Answer

The speed limit on some interstate highways is roughly 100 km/h . (a) What is this in meters per second? (b) How many miles per hour is this?

The speed of any object is referred to as the distance covered by a body in a given time period.

Velocity is the rate of change of distance with respect to time.

See the step by step solution

Step by Step Solution

Step 1: Defining velocity

The pace at which a body's distance changes in relation to time is referred to as its velocity. Its SI equivalent is m/s.

Given data

The speed limit v=100 km/h.

Step 2: (a) Explanation of velocity in meters per second

Write the equation for velocity.

v=100kmh1000 m3600 s =27.78 m/s

Step 3: (b) Explanation of velocity in miles per hour

As you know,-

1 km=0.621371 miles

Write the equation for velocity.

v=100kmh0.6214 miles =62.14 miles/h

Step 4: Conclusion

Hence, the velocity in meter per second is 27.78 m/s and in miles per hour is 62.14 miles/h.
