A train traveled 210 mi in 3.5 h to its first stop. It then continued on traveling another 130 mi in 2.5 h.
11111nata11111 [884]

Answer:

56.7 ​ mi/h​

The formula for average speed is:

Average Speed = \frac{TotalDistance}{TotalTime}


Thus we have:

Average Speed = \frac{210+130}{3.5+2.5}\\=\frac{340}{6}\\=56.66 mph


<em>Rounding to the nearest tenth, we have </em>

Average Speed = 56.7 mi/h

Remember you can do anything to an eqautoin as long as you do oit to both sides

-5x=15
try to get 1x by itself

remember
(ax)/a=x when a=a

so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3

answer is first one
