Scientists have measured a cheetah running across the savanna at 70 m/s. Which of these data accurately measured the cheetah’s speed? 480 m in 6 sec
600 m in 10 sec
210 m in 3 sec
300 m in 5 sec

210 m in 3 sec

Explanation:

The speed of the Cheetah is given to be 70m/s .

   We know that:

         Speed  =  

Now we find the choice that gives 70m/s:

480 m in 6 sec

          Speed  =   = 80m/s

600 m in 10 sec

           Speed  =   = 60m/s

210 m in 3 sec

            Speed  =   = 70m/s

300 m in 5 sec

          Speed  =    = 60m/s

So the solution is 210 m in 3 sec
