Answer:

280 meters

Explanation:

You should get the speed

And you should use the graph….

To get the distance using the graph the rule is …(area under graph) which is equal to area of triangle + area of the rectangle

Area of triangle = 0.5 x length x width

Area of rectangle = Length x width

(0.5 x 8 x 20 ) + ( 10 x 20 ) = 280 meters
