8:10 and 12:15

you can't apply division method to get the answer in integer form because the G.C.F. of 4 and 5 is 1. That means, 4 and 5 cannot be divisible by any other number except 1. 3.

IRISSAK [1]

ANSWER

114.52 meters per second

EXPLANATION

We have that the car covers a distance of 5726 meters in 50 seconds.

To find the speed, we have to use the formula for speed which is:

$\text{Speed = }\frac{dis\tan ce}{time}$

So, the unit rate of speed of the car is:

$\begin{gathered} \text{Speed = }\frac{5726}{50} \\ \text{Speed = 114.52 meters per second} \end{gathered}$

That is the unit rate of speed of the car in meters per second.

Answer:

solution,

$- 2 = \frac{x - 17}{2} \: \\ - 2 \times 2 = x - 17 \\ - 4 = x - 17 \\ - x = - 17 + 4 \\ - x = - 13 \\ x = 13 \\ \\ 7 = \frac{y + 17}{2} \\ 14 = y + 17 \\ - y = 17 - 14 \\ - y = 3 \\ y = - 3$

Therefore,

V=(13,-3)

Hope this helps...
