what is the equation for speed?

Question

can someone explain to me how to manipulate the equation for speed

and also. circumference only applies to circles right?

the equation for speed is
distance=rate x time, right?
well what does manipulate mean?

Answer 1

speed = distance over time
s=d/t
we can multiply the whole equation(both sides) by t/s
so
t/s(s)=d/t(t/s)
t=d/s
or multiply again by s(both sides)
s(t)=d/s(s)
st=d

yup circumference applies to anything related to circles...

Answer 2

Question 1
distance = d
speed = s
time = t
s = d / t

Question 2
Circles
d = diameter
r = radius
c = circumference

c = π d
c = 2 π r

Answer 3

Speed=Distance travelled/time taken.
Suppose u travelled 10km distance in 5seconds thn your speed=10/5=2.
Hope so you were able to understand.

Answer 4

speed means distance covered in a specific time unit. this means you have to compute distance covered in a specific unit. 80km/hour means. 80km distace covered in onehour.

this means

speed= distance / time


for km/h : distance and time must be in km and hour
for meter/second(m/s): distance and time should be in meter and seconds
and so on

============================================
the circumfece also applies for other figures. however formula is different.

Answer 5

speed=distance/time

for example, say if you go 10 miles (distance) in 2 hours (time), your speed would be 5 miles per hour.

Answer 6

Velocity=distance divided by time

Circumference applies to any continuous curved line ( e.g. circles and ellipses). If the figure has corners then it has a perimeter.

Answer 7

speed = d/t

So you could put it in terms of T = D/Speed or D = Speed(t)

And I think circumference could apply to ovals too, but at that piont it might be called perimeter.

Answer 8

distance/time

Answer 9

e=mc2
