Answer:
is it 0????????
Step-by-step explanation:
The difference between the average speed in km/h of their trains are 53.538 km/h.
Step-by-step explanation:
The given is,
Davit's train travels 90 km in 50 minutes.
Mila's train travels 210 km. It leaves at 12:05 and arrives 13:35.
Step:1
From the given,
Time required to milas train travels 210 km
= 12:05 - 13:35
= 1.30 hours
Step:2
Time to Davit's train travels 90 km is need to convert in hours from minutes,
= 50 minutes
=
hours
= 0.833 hours
Step:3
Average rate of Davits train,
= ![\frac{Distance traveled}{Time taken}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%20traveled%7D%7BTime%20taken%7D)
= ![\frac{90}{0.833}](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B0.833%7D)
= 108 km/h
Step:4
Average rate of Mila's train,
= ![\frac{Distance traveled}{Time taken}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%20traveled%7D%7BTime%20taken%7D)
= ![\frac{210}{1.30}](https://tex.z-dn.net/?f=%5Cfrac%7B210%7D%7B1.30%7D)
= 161.538 km/h
Step:5
The difference between the average speed of the both trains in km/h,
= 161.538 - 108
= 53.538 km/h
Result:
The difference between, the average speed of their trains are 53.538 km/h.
Answer:
The red dot is ( a, f ( a )), the blue dot is ( b, f ( b )), and the magenta dot is ( c, f ( c )). The secant line segment connecting a and b is shown, as is its slope. The Mean Value Theorem says that there exists a value of c between a and b such that the slope of f at c is the same as the slope of the secant.

Answer:
-1/5
Step-by-step explanation:
x+3x−4=5−(x+10)
x+3x−4=5+−1(x+10)(Distribute the Negative Sign)
x+3x−4=5+−1x+(−1)(10)
x+3x−4=5+−x+−10
x+3x+−4=5+−x+−10
(x+3x)+(−4)=(−x)+(5+−10)(Combine Like Terms)
4x+−4=−x+−5
4x−4=−x−5
Step 2: Add x to both sides.
4x−4+x=−x−5+x
5x−4=−5
Step 3: Add 4 to both sides.
5x−4+4=−5+4
5x=−1
Step 4: Divide both sides by 5.
5x
/5
=
−1
/5
(sorry this was long hope this helps)
I think the answer is 5.73
Hope this helps
