Distance=rate times time
distance=460
rate-wind=rate against wind
rate+wind=rate with wind
2.5=time aginst wind
2=time with wind
so
460=(rate-wind) times 2.5
and
460=(rate+wind) times 2
solve for rate
460=(rate-wind) times 2.5
divide both sides by 2.5
184=rate-wind
460=(rate+wind) times 2
divide by 2
230=rate+wind
we have
184=rate-wind
230=rate+wind
add them
184=rate-wind
<u>230=rate+wind +
</u>414=2rate+0wind
414=2rate
divide by 2
207=rate
answer is 207 miles per hour
Answer:

Step-by-step explanation:
Answer: x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−x−1=15
3x+−x+−1=15
(3x+−x)+(−1)=15(Combine Like Terms)
2x+−1=15
2x−1=15
Step 2: Add 1 to both sides.
2x−1+1=15+1
2x=16
Step 3: Divide both sides by 2.
2x
/2
=
16
/2
x=8
