Can you check my work @Shalante? A cheetah is known to be the fastest mammal on Earth, at least for short runs. Cheetahs have been observed running a distance at \(5.00\times10^2\)m with an average speed of \(1.00\times10^2\)km/hr. How long would it take the cheetah to cover this distance at this speed? I first converted to m/s and I got the time to be 19.8s, is that right?

Best ResponseYou've already chosen the best response.1I did 27.78m/s=550m/t. I then divided 550m by 27.78m/s and got 19.8s

Best ResponseYou've already chosen the best response.0\[\frac{ 100km }{ 1 hour }\times \frac{ 1000m }{ 1km }\times \frac{ 1hour }{ 60minutes }\times \frac{ 1minute }{ 60seconds }\]= 27.7m/s Notices 100km/1hr is the same as 100km/hr. 27.7m/s is velocity To get time=distance over velocity t=500m/27.7m/s=18.0s

Best ResponseYou've already chosen the best response.0It is 500m not 550m 5.00 x10^2m is 500m. Unless you posted the wrong number

Best ResponseYou've already chosen the best response.1it is "suppose the average speed of the cheetah were just 85.0km/hr. What distance would the cheetah cover during the same time interval calculated in a?"

Best ResponseYou've already chosen the best response.1I already converted it into m/s and got 23.61m/s

Best ResponseYou've already chosen the best response.1I got 467.5m... is that correct?

Best ResponseYou've already chosen the best response.023.61m/s*19.8s=476.5m You are correct 4.74 x10^2m tho since we are multiplying and dividing and least sf in original value is 3. Brb let me switch computers. (In school)

Best ResponseYou've already chosen the best response.1woe... why 4.74?

Best ResponseYou've already chosen the best response.0Actually, it is better to round it off 467.5m becomes 467m. I was rushing when I shut down the computer lol. 2 mistakes already.

Best ResponseYou've already chosen the best response.0If answer is in 4 sf then shortest sf is 3 then you do scientific notation Ex: 5067m is answer. Least sf is 3 5.07x10^3m

Best ResponseYou've already chosen the best response.0and shortest sf is 3, then you Typing so fast with this nice keyboard. Making lots of typos and such.
