20,825 because I think you just multiply 245 and 85 and that should be the answer
Answer:
Step-by-step explanation:
let the speed of one plane=x
speed of other plane=x+80
time=4 hrs
then 4x+4(x+80)=3800
4x+4x+320=3800
8x=3800-320
or 8x=3480
x=435
speed of one plane=435 m/h
speed of other plane=435+80=515 m/h
2.
Let he walks x hrs
then he take a taxi for 2-x hrs
4x+(2-x)50=31
4x+100-50x=31
-46x=-69

so he walks 3/2 hrs=1.5 hrs
travels by taxi=2-1.5=0.5 hrs
distance traveled by taxi=0.5×50=25 miles

Hey there!
The answer is 
We will start by forming an equation to solve this.
So we are starting with a number,
, then doubling it and adding
, which gives us 25.
So:

Now we solve this equation:



Have a super awesome day!
