You drove for half the time at 60mph and the other half the time at 30mph.
To find your average speed, we add 60 and 30 then divide them by two (because you drove at 2 different speeds). 60+30 = 90 and 90/2 = 45 so 45 miles per hour is your average speed.
Note: Velocity implies a direction to the force and there is no direction in this question, just speed. Without direction we cannot use velocity, only speed.
Answer:
it would be 2d - 60
Step-by-step explanation:
Because if you susbtract d from 3d it would be 2d cause d is like a number in this unit
I think point E is the correct answer.
Answer:
This as a decimal number would be 2.5.
Step-by-step explanation:
In order to find this, start by dividing the fraction in a calculator.
1/2 = .5
Now we simply add that to the whole number.
2 + .5 = 2.5
