Can someone help me calculate speed?

Question

1) 2 meters in 1.67 seconds

2) 4 meters in 2.17 seconds

3) 6 meters in 3.62 seconds

--------------------------------------...

1) 2 meters in 1.48 seconds

2) 4 meters in 3.26 seconds

3) 6 meters in 10.81 seconds

i need help please :(

Answer 1

speed = (distance)/(time)

so in this case...

1.  speed=2m/1.67s or 2/1.67 m/s

2.  speed= 4m/2.17s or 4/2.17 m/s

3.  speed = 6m/3.62s or 6/3.62 m/s

follow this on the next set, hope this helps

Answer 2

The formula is:

V=d/t

V=speed (velocity)

d=distance(meters)

t= time (seconds)

Plug it in!

:)

Answer 3

note

d = rt

2 = r(1.67)

r = 2/1.67

r = 1.97605 m/sec

Answer 4

speed is meters per second. all you have to do is divide 2/1.67, 4/2.17 and so on

Answer 5

speed (v) = distance (d) / time (t)

v = d/t

so u can calculate every one u put here

you will get

1.2 m/s (meter/second)

1.84 m/s

1.66 m/s

1.35 m/s

1.23 m/s

0.56 m/s

if u want it in Km/h

1 m/s = 3.6 Km/h (kilometer/hour)
