Respuesta :
Nicki rides her bike at a constant speed for 6 km. That part of her ride takes her 1 hour. She then rides her bike at a constant speed for another 9 km. That part of her trip takes her 2 hours. Her average speed is 5m/s
Based on the given conditions, formulate: [tex](9+6) \div($ $2+1)$[/tex]
Calculate the sum or difference: [tex]$\frac{15}{2+1}$[/tex]
Calculate the sum or difference: [tex]$\frac{15}{3}$[/tex]
Reduce the fraction: 5 m/s
get the result: 5 m/s
What is average speed?
- The overall distance travelled by the object in a given time frame is the average speed. A scalar quantity is average speed. It is expressed by magnitude and lacks direction.
- Distance travelled divided by time taken is the most often used formula for calculating average speed. The alternate formula is to add the beginning and end speeds together and divide by two.
- The average is just the sum of all the numbers divided by the total number of values. The mathematical average of a group of two or more data values is defined as a mean. Average is also known as mean or arithmetic mean. Mean is merely a way of summarising the sample's average.
