PLEASE HELP!! I’m very confuse

Given:

A(16, 4)

B(34, 40)

Line segment AB partition in the ratio 1 : 5.

To find:

The coordinate of a point that partitions AB.

Solution:

Section formula:

$$P(x,y)=\left(\frac{m x_{2}+n x_{1}}{m+n}, \frac{m y_{2}+m y_{1}}{m+n}\right)$

Here $x_1=16, y_1=4, x_2=34, y_2=40$ and m = 1, n = 5

$$P(x,y)=\left(\frac{1\times 34+5 \times 16}{1+5}, \frac{1\times 40+5 \times4}{1+5}\right)$

$$P(x,y)=\left(\frac{ 34+80}{6}, \frac{40+20}{6}\right)$

$$P(x,y)=\left(\frac{ 114}{6}, \frac{60}{6}\right)$

$$P(x,y)=(19, 10)$

The coordinate of point that partitions the segment AB is (19, 10).

Kevin needs to convert 620 millimeters per minute to meters per hour. Which conversion factors should he use?

Annette [7]

Try this option:
1 meter=1000 mm; 1 hour=60 min. From another side: 1 mm=0.001 m. and 1 min=1/60 h.
Using this rule:
620 mm/h=0.06*620 m/h=37.2 meters per hour.
