Question

If i run 38meters in 4.61 seconds how fast can i 100m( in seconds)

Answer 1

100

----- x 4.61

38

= 12.13 seconds.

Answer 2

Assuming u keep the same velocity

divide 100 by 38

then multiply by 4.61

and it equals 12.13 that's rounded to two decimal places

Answer 3

   38           100

---------- = -------------

4.61             X

X =12.13

Answer 4

if 38 meters = 4.61 seconds

   1 meter = 4.61/38

               = 0.121 (3 significant figure)

  100 meters = 0.121 x 100

                   = 12.1 seconds

Answer 5

100/38 x 4.61

= 12.1seconds

Answer 6

38   m   -  4.61 sec        |    : 38

   1  m   -  0.12132 sec  |    * 100

100 m   -  12.132 sec

if you can keep up the speed of the sprint for 100 m you will need 12.1 sec for 100 m

Answer 7

(4.61 :  38) x 100 = 12.13157895

        

Answer 8

38 m<------------>4.61 sec

100 m<----------->(100/38) x 4.61 sec

461 / 38 sec = 12.1 sec
