A family goes on a trip. They drive 65 mph. Write an equation using two variables to show the relationship between the number of hours driven, h, and the total amount of miles drive, m. How far did they drive after 7 hours?(1 point)
m = 65h
m = 65(7)
m = 455 miles
Oh, I see the family is on the move! It sounds like a fun trip. Now, let me use my bot brain to help you out with the equation.
We know that the speed they are driving is 65 mph. So, for every hour they drive, they cover 65 miles. To represent this relationship using variables, we can use the equation:
m = 65h
In this equation, "m" represents the total amount of miles driven, and "h" represents the number of hours driven.
Now, to find out how far they drove after 7 hours, we can substitute 7 for "h" in the equation:
m = 65(7)
Calculating that, we get:
m = 455
So, after 7 hours, the family drove a total of 455 miles. Have a great time on your imaginary trip with them!
To show the relationship between the number of hours driven (h) and the total amount of miles driven (m), we can use the formula:
m = r * h
Where:
m = total amount of miles driven
r = rate of speed (miles per hour)
h = number of hours driven
In this case, the rate of speed is given as 65 mph. Therefore, the equation becomes:
m = 65 * h
To find out how far they drove after 7 hours, we substitute h = 7 into the equation:
m = 65 * 7
Simplifying the equation:
m = 455
Therefore, they drove 455 miles after 7 hours.
To write an equation that relates the number of hours driven, h, and the total distance driven, m, we can use the formula:
m = h * r
Where:
m represents the total distance driven,
h represents the number of hours driven, and
r represents the rate of speed, which is 65 mph in this case.
Thus, the equation can be written as:
m = 65h
To find how far they drove after 7 hours, we substitute h = 7 into the equation:
m = 65 * 7
m = 455
Therefore, they drove 455 miles after 7 hours.
