Jesse Rose walks along a footpath for 6 minutes.She then cuts across a field, which takes a further 4 minutes.She walks a total distance of 900m.
what is her average speed?
could you please explain this step by step.
900 / (6 + 4) = ________ meters per minute
the answer it gave me is 1.5m/s
so? can anyone else help me
Yes. 90 meters per minute equals 1.5 meters per second.
okay sorry my bad could you explain it to me how do you done it
I showed you how to find the number of meters per minute.
Divide 90 by 60 to get 1.5 meters per second.
To calculate Jesse Rose's average speed, we need to determine the speed at which she walks and the time it took to cover the total distance traveled.
Step 1: Calculate the total time taken
Jesse Rose walked on the footpath for 6 minutes and then cut across the field for an additional 4 minutes. Therefore, the total time taken is 6 minutes + 4 minutes = 10 minutes.
Step 2: Convert the time to hours
Since speed is usually measured in terms of distance covered per unit of time (e.g., kilometers per hour), we need to convert the time from minutes to hours. There are 60 minutes in an hour, so we divide the total time by 60:
10 minutes ÷ 60 minutes/hour = 0.1667 hours.
Step 3: Calculate the average speed
Average speed is defined as the total distance traveled divided by the total time taken. In this case, the total distance traveled is given as 900 meters. Therefore, the average speed is:
Average speed = Total distance ÷ Total time
Average speed = 900 meters ÷ 0.1667 hours.
To find the result, divide 900 meters by 0.1667 hours.
Therefore, Jesse Rose's average speed is approximately 5400 meters per hour.
