Question

. Given the following the numbers use the contained units to tell if the number is
describing distance, speed, or velocity.
A. 150 km __________
B. 65 m/s east __________
C. 12 km/h __________
D. 78 cm __________
E. 34 cm/min to the left __________

Answer 1

Answer:

A: Distance

B : Velocity

C: Speed

D : Distance

E : velocity

Explanation:

We have the proper description about these terms:

Distance : It is the total path traveled by body irrespective of direction .

Its unit is m/Km/cm/m .

Speed : It is distance traveled by body with respect to time taken .It does not specifies direction .

Its unit is m/sec ,Km/hr

Velocity : It is distance traveled by body with respect to time taken in a given direction  .It  specifies magnitude and direction both

Its unit is m/sec (direction ),Km/hr (direction also ).

Answer 2

The statement A and D resembles the distance. Statement B and E resembles the velocity. And statement C resembles the speed.

The given problem is based on the concept of distance, speed or velocity. The proper definition of each of the following terms is given as follows:

• Distance : It is the total path traveled by body irrespective of direction . Its units are m , Km, cm and m .

• Speed : It is distance traveled by body with respect to time taken. It does not specifies direction.  Its unit is m/sec  and Km/hr.

• Velocity : It is distance traveled by body with respect to time taken in a given direction  .It  specifies magnitude and direction both . Its unit is m/sec (direction ),Km/hr (direction also ).

So, 150 km and 78 cm are the units resembling the distance.

65 m/s and 34 cm/min to left resembles the velocity.

And, 12 km/h resembles the speed.

Thus, we can conclude that the statement A and D resembles the distance. Statement B and E resembles the velocity. And statement C resembles the speed.
