Question
Jamie started running at a speed of 2.8 m/s.After a while, she increased her speed by 50%.Find Jamie's speed after she increased from her original speed.
Solution
To find Jamie's speed after she increased it by 50%, we need to calculate 50% of her original speed and then add it to her original speed.
Step 1: Find 50% of Jamie's original speed 50/100 * 2.8 m/s = 1.4 m/s
Step 2: Add the increase to the original speed 2.8 m/s + 1.4 m/s = 4.2 m/s
So, Jamie's speed after she increased it from her original speed is 4.2 m/s.
