Seems to me that it flies 400 m/s there and 600 m/s back the same distance.
therefore the average of 400 and 600 is 500 m/s. The distance is the same so the normal formula of (d2-d1)/(t2-t1) is applicable.
Use the largest force for as long a time as possible Ft=mV.
Hope this help
Answer: concentration c = 25.2 g /(41.99 g/mol × 0.75 l)
Explanation: M(NaF) = 41.99 g/mol and amount of substance n = m/M.
Concentration c = n/V
the speed would have to be somewhere between 1.667 or 1.666 miles per minute.
add 30, 15, 5 together and you will get 50
50 is the total miles traveled
then you multiply 30 by 1.666 and you will get 49.98 but it's still not quite 50 miles
if you multiply 30 by 1.667 and you will get 50.01 but its a little over to miles
i got the 30 from the minutes traveled
anyway that's the best i got for speed
