Weekly Maths Problem

Don’t forget to write out the problem at the top of the page, date the work and show all your workings out (even the wrong answers) and then file the evidence in your folder!

Ella loves to compete in Windsor Doggy Triathlons with her dog Hazel. At a race a few days ago, Ella and Hazel finished in 220 minutes. Yesterday, the weather was not so good. They did another training session and finished in 275 minutes. What was the percent of increase in Ella and Hazel's finishing time?

You can share your answers here on Facebook or in the forum or with me as I visit during the week. Remember you need to show your workings out to get the maximum points.
