Just use the basic equation for speed: distance = speed x time.

Don't worry about the speed limit and the stop lights. You don't need them,

they don't help, and they're not involved in deriving the answer. Among

higher mathematicians, items like these are referred to as "red herrings".

A car travels 70 miles in 80 minutes. Which is its average speed per minute?

Simple Equation Speed = Distance / Time as you want it in a speed distance per minute, the time in this equation is in minutes. it will result in a unit of miles per minute. 70 divided by 80 = 0.875 so the average speed is 0.875 Miles per Minute


A cyclist travels at an average speed of 16 km how will he travel in 45 minutes?

16 km is not a speed (average or otherwise), it is a distance. It is therefore impossible to answer this question.

How many minutes before 10 AM is it if 90 minutes later it will be as many minutes after 11AM?

If 90 minutes after a certain time is the same number of minutes after 11 AM, we can set up the equation. Let ( x ) be the number of minutes before 10 AM. Then, ( 10 AM - x ) gives us the time. 90 minutes later would be ( 10 AM - x + 90 ), and it needs to equal ( 11 AM + x ). Setting the equation gives us ( 10:00 - x + 1:30 = 11:00 + x ). Solving this, we find ( x = 30 ). Therefore, it is 30 minutes before 10 AM.

A student walks 0.85 km to class in 5 minutes and then back in 7.1 minutes What is his average velocity?

The total displacement is 0 km, as the student returns to the starting point. The total time taken is 5 minutes + 7.1 minutes = 12.1 minutes. Therefore, the average velocity is 0 km divided by 12.1 minutes, which equals 0 km/min.


What is an equation for the question how many minutes in two hours?

Let's translate the sentence into an equation: How many minutes are in two hours? Let x represents the number of minutes we are looking for, then: x (in minutes) = 2 hours Now we need to convert hours into minutes. Since there are 60 minutes in an hour, in 2 hours there are 2 * 60 = 120 minutes. So: x = 120 minutes.


How many minutes does it take an average person to walk a mile?

20 minutes is average.


How many hours in 900 minutes?

To convert minutes to hours, you divide the number of minutes by 60 since there are 60 minutes in an hour. Therefore, 900 minutes divided by 60 equals 15 hours.


An airplane travels 80 km in 10 minutes and then flies 100km in 20 minutes the average speed of the plane is?

The total distance covered by the plane is 80km + 100km = 180km, and the total time taken is 10 minutes + 20 minutes = 30 minutes. Therefore, the average speed of the plane is 180km / 30 minutes = 6 km per minute.


What is the average speed of 30km in 48 minutes?

To find the average speed, divide the total distance traveled by the total time taken. In this case, 30 km / 48 min = 0.625 km/min. Therefore, the average speed is 0.625 kilometers per minute.
