Speed Formula Help!!!?

Question

The speed of a swimmer who swims 150 meters in 88 seconds? All I know is that I need to find the speed, and that the formula is d/t=s.....HELP!!!

Answer 1

When the question is framed in terms of meters and seconds then the answer should always be presented in meters per second, NOT converted to km/h. It makes it more complicated, you wont get extra marks for it and you could actually lose marks.

Answer 2

d/t=s

Where,

     d = diatance

     t = time

     s = speed

So,

     Speed (s) = Distance (d) / Time (t)

                       = 150 meters/ 8 seconds

                       = 18.75 meters/second

Answer 3

no actually ... usually they calculate speed in schools in m/s .. so the first guy is correct ... 150/88 = 1.7 m/s

Answer 4

88 secs is x% of an hour, and you need to find out how far they would have gone had they swam at that rate for the entire hour, therefore the formula is:

no of secs in an hour (3600) divided by the no of seconds recorded (88) times how far they did travel (150m)

(3600 / 88) x 150m = 6.14kph

Answer 5

______

Data :

----------

d = 150m

t = 88sec

v = ?

_______

Solution :

-------------

By using the formula, we have

d = v*t

v = d/t

v = 150/88

v = 1.7045 m/s

Answer 6

Formula is correct. However, you shall convert it into distance/hrs

So distance in Km / Time in Hrs will give you correct speed.

e.g. 150/1000 is 0.150 KM and 88/3600 is time in hrs Now make division

Answer 7

Distance/time = speed, Think of it this way, It means a certain amount of distance covered in unit time.

So The answer is 150/88 =~ 1.70 m/p

Answer 8

d = distance

t = time

s= speed

so the speed will be 150/88

the answer will be in meters per second (m/s) as they are the units you used in the calculation.
