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.


Darren can be at work in 30 minutes. The speed limit is 35 mph and there are three stop lights. Therefore due to traffic he can only average 30 mph. How far is he from work Click on the equation that?

To find the distance Darren is from work, you can use the formula: distance = speed × time. If Darren can average 30 mph and takes 30 minutes (which is 0.5 hours), the distance is calculated as follows: distance = 30 mph × 0.5 hours = 15 miles. Therefore, Darren is 15 miles away from work.


Is 20 minutes a long time?

Time is relative. Therefore, if you take 20 minutes to walk 200 yards then 20 minutes is a long time. However, relative to an average lifetime, 20 minutes is a very short amount of time.


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.


What IS the average speed if you travel 3km in 15 minutes?

To find the average speed, you divide the distance by the time taken. In this case, the distance is 3 kilometers and the time is 15 minutes. First, convert 15 minutes into hours, which is 0.25 hours. Therefore, the average speed is ( \frac{3 \text{ km}}{0.25 \text{ hours}} = 12 \text{ km/h} ).


How many minutes in a month on average?

On average a month has 302400 minutes.


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?

An airplane travels 80 km in 10 minutes and then flies 100km in 20 minutes the average speed of the plane is? 80 km in 10 minutes = 8 km/min 100km in 20 minutes = 5 km/min Average speed = total distance traveled ÷ total time Average speed = 180 km ÷ 30 min = 6 km/minute Notice the average speed is closer to 5 km/min, because the plane spends twice as much time traveling at the slower speed.
