A body at rest is given an initial acceleration is 7m/s^2 for 30seconds after which the acceleration is reduced to 5m/s^2 for the next 20seconds. The body maintain the speed of 60m/s after which it is brought to rest in 20 seconds. Calculate the average speed

Look it up you feel me

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
