An olympian swam the 200-meter freestyle at a speed of 1.8 meters per second. An olympic runner ran the 200-meter dash in 21.3 s

Maurinko [17]

Answer:

7.6m/s

Step-by-step explanation:

Find the time the Olympian swam

Speed=distance/time ⇒⇒Time=distance/speed

Distance=200m , speed= 1.8m/s t= 200/1.8 = 111.11 seconds

Find the speed of the Olympic runner

Distance=200m time = 21.3 sec

s=200/21.3 = 9.4 m/s

Difference in speed= 9.4-1.8= 7.6m/s

So in this problem we can see that there will be 60 people at the party. Following the conditions for this event that state the following: $750 for up to 30 people and every extra person pays $20. To show that the cost will be $1350 in total we simply do this:

For 30 people we have $750 dollars. Now every other person after pays only $20. That means that another the other 30 people will pay in total only $600.

If we add them we get: $750 + $600 = 1350. This shows that the cost will be $1350.
