<h2>Answer:</h2>

The term speed is used to denote distance  traveled divided by time. The speed is the magnitude of instantaneous  velocity and so can never be negative. In this problem, we have a boat’s velocity measured in meter per second, described by vector:

b=(3,-4)

1. Therefore, the magnitude of this vector, which is also the speed of the boat can be found as:

\left|b\right|=\sqrt{3^2+(-4)^2}=5m/s

2. On the other hand, the direction the boat is traveling is the angle that this vector makes with the horizontal. So this can be found as:

\theta = tan^{-1}(\frac{3}{-4})=-36,86^{\circ}

The representation of this problem is shown below.

They will need 2 5/12 more pounds to reach their goal.

<h3>Sum and difference of fractions</h3>

Given the following information as shown:

  • Amount Blake collected = 6 1/3 pounds
  • Amount his brother collected = 5 3/4 pounds

If their goal is to collect 14 1/2 pounds of food by the end of the month, the remaining food they need to collect will be expressed as:

y =14 1/2 - (6 1/3 + 5 3/4)

y = 14 1/2 - (19/3  + 23/4)

y = 29/2 - (76+69/12)

y = 29/2 - (145/12)

y = 174-145/12

y = 29/12

y = 2 5/12

Hence they will need 2 5/12 more pounds to reach their goal.
