this week in science we kept on practicing with the formulas that we know to find speed on a graph. what we have learned is that in order to find the speed of jsomething on a graph you have to get the dealta positon which is what was the change of position over time then you have to divide that by delta time which is the change of time. for example if you had a 35 positoion change and a 75 time change then you have to divide 35 by 75 which is .47 is your speed. at the end of the week we had a quiz on all that we wree learning about this then the week eneded.
