Laura, David, and Carlos served a total of 115 orders Monday at the school cafeteria. David served 3 times as many orders as Car
Korvikt [17]

Answer:

Step-by-step explanation:    ts  6  11    19    56

Laura, David, and Carlos served a total of 115 orders

David served 3 times as many orders as Carlos.                 David = 3x

Laura served 10 more orders than Carlos.                      let Carlos = x

How many orders did they each serve?                           Laura  =  x + 10

     Carlos  +  David  +  Laura  = 115

          x  +     3x    +    x+10       = 115

                        5x + 10     =  115

                               5x   =  115 - 10

                               5x   =  105

                                x   =   21    Carlos

                                          63   Davide

                                          31    Laura

                 add then up    115  Total

A motorcycle zoomed along the freeway, traveling 10 meters in
Hoochie [10]

The speed of the motorcycle will be 30 meters per second.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

A motorcycle zoomed along the freeway, traveling 10 meters in 1/3 of a second.

Then the speed of the motorcycle will be

Speed = 10 / (1/3)

Speed = 10 x 3

Speed = 30 meters per second

The speed of the motorcycle will be 30 meters per second.

More about the speed link is given below.
