mr. Niba lives 400m due east of school while mr. Ako lives due south of the same school. i. draw a vector diagram to represent this information ii. find the distance covered by Ako child to reach the school

To represent this information on a vector diagram, you can draw two arrows - one pointing 400m due east to represent Mr. Niba's position relative to the school, and another arrow pointing due south to represent Mr. Ako's position relative to the school. The length of the arrow representing Mr. Ako's position can be arbitrary, as long as it is different in size compared to the arrow representing Mr. Niba's position.

To find the distance covered by Mr. Ako's child to reach the school, we need more information. We need to know the distance from Mr. Ako's house to the school. The information provided only tells us his position relative to the school, but not the actual distance.
