Question
Jennifer started running at a speed of 3 m/s.After a while, she increased her speed by 30%.Find Jennifer's speed after she increased from her original speed.Express your answer as a decimal.
Solution
-
First, we need to find out how much Jennifer increased her speed by. We do this by multiplying her original speed by the percentage increase. In this case, that's 3 m/s * 30/100 = 0.9 m/s.
-
Next, we add this increase to Jennifer's original speed to find her new speed. That's 3 m/s + 0.9 m/s = 3.9 m/s.
So, Jennifer's speed after she increased it from her original speed is 3.9 m/s.
