Acar is traveling at a speed of 20 meters per second. what is the cars speed in kilometers per hour

72 km/h

Step-by-step explanation:

We need to convert units

so:

20 m      1 km 3600 s

1 s          1000 m 1 h

and solve ot

20 x 1 x 3600 s = 72000  we multiply  numerators

1s x 1000 m x 1 h = 1000  we multiply denominators

we divide de results 72000/1000 = 72

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
