harina [27]

Answer:

The hummingbird travels the total distance is 10 m

Explanation:

Given that,

A hummingbird flies forward and backward.

According to figure,

We know that,

The total distance is equal to the sum of all distance.

Forward direction is positive and backward direction is negative.

We need to calculate  the hummingbird travels the total distance

Using figure,

D=d_{1}+d_{2}+d_{3}+d_{4}

Put the value into the formula

D=6+(-4)+2+6

D=10\ m

Hence, The hummingbird travels the total distance is 10 m.
