A car travels a total distance of 150km. At the 50 minutes mark the car has travelled 50km and at the 110 minutes the car has tr
Nitella [24]

Answer:

The average velocity is 19.44 m/s.

Step-by-step explanation:

The average velocity between two points can be calculated with the following formula:

\bar v=\dfrac{\Delta X}{\Delta t}=\dfrac{(120-50)\, km}{(110-50)\, min}=\dfrac{70\,km}{60\,min}\\\\\\\bar v=1.667\dfrac{km}{min}*\dfrac{1\,min}{60\,s}*\dfrac{1000\,m}{1\,km}=19.44\dfrac{m}{s}

The procedure is to calculate the difference for both distance and time, and dividing the two differences, we get the average velocity.

An expression to convert 50 miles per hour to miles per minute is shown.
Nataliya [291]
Use the fact that 1 hour = 60 minutes, from which you can create your conversion factor: 1 = hour / 60 minutes. That permit you to multiply the number of miles per hour times [1 hour/60minutes] to convert 50 miles per hours to miles per minute. This is the calculation: 50 miles/hour * [1hour/60minures] = 0.833 miles / minute
