Question

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

Answer 1

210 m in 3 sec

Step-by-step explanation:

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

We know that:

Speed =
`(distance )/(time)`

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

480 m in 6 sec

Speed =
`(480)/(6)` = 80m/s

600 m in 10 sec

Speed =
`(600)/(10)` = 60m/s

210 m in 3 sec

Speed =
`(210)/(3)` = 70m/s

300 m in 5 sec

Speed =
`(300)/(5)` = 60m/s

So the solution is 210 m in 3 sec
