11.The length of a rectangle is 10 more than the width, sketch the rectangle and label the length and the width and then write an expression that could be used to express the area of the rectangle.

width would be X and length would be X+10

A=X*10x

70,000 + 6,000 + 800 + 30

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
