Answer:
the answer would be A i believe
50 m/s is going to be 180 km/h or 3 km/s.
50 / 1000 = 0.05
0.05 x 60 = 3 kilometers a minute.
3 x 60 = 180 kilometers an hour.
50 m/s divided by 1 kilometer = 0.05 kilometers a second. You then multiply it by 60 to get it in minutes, and then 60 again to get it in hours. because their are 3600 seconds in an hour. So you could divide 50 meters per second by 1000 meters or 1 kilometer and then multiply it by 3600 seconds to get 180 kilometers an hour.
Answer:
you can combine like term such as x or 2x, but not variables with different exponents like x and x squared.
Step-by-step explanation:
If x=10 than f(x)=1 because 2+8=10/10 =1
