A track star runs the 220.0 meter run in 23.2 seconds. What would be his time, in seconds for a 440.0 run if ran it at the same rate? 1 in= 2.54cnm

I have to make sure to put it in correct significant figures for chemistry

CHEMISTRY: Would I have to convert the 440 yards into meter first?

440 m is twice 220 m
So he wold take twice as much time.
What would that be?

1 m = 1.09361 yd
220 m = 240.592 yd
r represents his rate
240.592 : 23.2 :: 440 : r   proportion
240.592r = 440(23.2)       product means/extremes
Can you solve for r?
