Answer:

About 40 Minutes, Or something close to that

Step-by-step explanation:

The car covers 60 km in 90 minutes or its speed = 60 km*60/90 min = 40 km/hr . So to cover 100 km at the same speed it will take 100/40 = 40 Min

Answer:

It is the experimental condition.

Step-by-step explanation:

In the experiment given in the question, the amount of sleep is the independent variable and the number of photographs they remember is the dependent variable because it depends on the amount of sleep.

The 8 hours of sleep, which creates the difference in the experiment between the control group and the test group, is the experimental condition.

The experimental condition is the variable that is changed to let the researcher observe the effects on the dependent variable.

eduard

Answer:

11/6

Step-by-step explanation:

<u>Step 1:  Convert to Improper fractions</u>

3 1/3 = 3*3/3 + 1/3 = 9/3 + 1/3 = 10/3

1 1/2 = 1*2/2 + 1/2 = 2/2 + 1/2 = 3/2

<u>Step 2:  Make common denominators</u>

10/3 * 2/2 = 20/6

3/2 * 3/3 = 9/6

<u>Step 3:  Subtract</u>

20/6 - 9/6

11/6

Answer:  11/6
