we are given

Jimmy is trying to escape Jane

For finding total distance , we will find distances and then add them

He runs 12 km/hr for 5 minutes

First distance:

speed =12 kh/hr

time=5 minutes

we can change into hour

t=\frac{5}{60}hr

d_1=s*t

now, we can plug values

d_1=12*\frac{5}{60}

d_1=1

second distance:

speed =17 kh/hr

time=8 minutes

we can change into hour

t=\frac{8}{60}hr

d_2=s*t

now, we can plug values

d_2=17*\frac{8}{60}

d_2=2.26667

third distance:

speed =6 kh/hr

time=2 minutes

we can change into hour

t=\frac{2}{60}hr

d_2=s*t

now, we can plug values

d_3=6*\frac{2}{60}

d_3=0.2

now, we can find total distance

d=d_1+d_2+d_3

d=1+2.26667+0.2

d=3.46667

so,

total distance is 3.46667 km...........Answer

lapo4ka [179]

Answer:

Easter, Christmas, birthdays, and New Year

Step-by-step explanation:

For me, I would choose Easter because before easter we always go to a church and stay there whole night. After 3-4 a.m, we go home and take a nap. But the most fun activity that we do during Easter is playing a game where we pick the best eggs and beat with each other. Later, our parents hide eggs and a couple of toys in the park and me and my siblings begin finding them.

Answer:

the combination of numbers must then be:

9.7 + 8.6 which results to 18.3

9.6 + 8.7 yields 18.3 as well.

LMK if I was wrong.

The equation of the line that goes through the point (−10,8) and (−3,-4) can be written in the form y=mx+b
Y_Kistochka [10]

Answer:

m is -12/7 and b is -64/7

Step-by-step explanation:

Use rise over run (change in y / change in x) to find the slope, m:

(-4 - 8) / (-3 + 10)

= -12/7

So, m is -12/7.

Plug in this value and a point into y = mx + b, then solve for b:

y = mx + b

-4 = -12/7(-3) + b

-4 = 36/7 + b

-64/7 = b

So, m is -12/7 and b is -64/7
