<span>The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.
Explanation<span>:
We start out with the ratio 207 km/1 hr.
We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.
We know that 1 hr = 60 minutes, so we have 207000 m/60 min.
We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.
Dividing this, we get 57.5 m/s.
In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.</span></span>

Answer:
x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+3−2x=24
Step 1: Simplify both sides of the equation.
5x+3−2x=24
5x+3+−2x=24
(5x+−2x)+(3)=24(Combine Like Terms)
3x+3=24
3x+3=24
Step 2: Subtract 3 from both sides.
3x+3−3=24−3
3x=21
Step 3: Divide both sides by 3.

Answer:
18.18%
Step-by-step explanation:
Percent change formula:
(new amount - old amount)/(old amount) * 100%
new amount: 6500
old amount: 5500
percent change:
(6500 - 5500)/5500 * 100% = 18.18%
