HEYOO PEEPS I KINDA NEED HELP Calculate the average speed of the four team members. Each person ran 50 meters. Tray ran 50 meters in 12 seconds,

Riley ran 50 meters in 8 seconds,

Sara ran 50 meters in 10 seconds and

Nate ran 50 meters in 10 seconds.

What is the average speed of the team members? Don't forget the units.

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

5.10 m/s

The "m/s" means "meters per second". The value is approximate.

Explanation:

Recall that

distance = speed*time

which we can isolate the speed to get

speed = distance/time

You divide both sides by time and flip both sides.

So that explains why for example Nate's speed is (50 meters)/(10 seconds) = 5 m/s. The other runners are calculated the same way.

You should get the following speeds for each runner

Tray = 4.167 m/s approximately

Riley = 6.25 m/s

Sara = 5 m/s

Nate = 5 m/s

Only Tray's value is approximate since the decimal number goes on forever. I rounded to three decimal places. The other values are exact.

Once we have these four speed values, we add them up and divide by 4 to find the average speed overall of the group.

(4.167+6.25+5+5)/4 = 5.10425

The average speed of the team is roughly 5.10 m/s

Extra info (optional section)

To convert from m/s to mph, you will multiply by roughly 2.237

For example, 5 m/s turns into 5*2.237 = 11.185 mph, which is approximate.
