the tunnel is 1400 ft. long cuz if it goes thro at 20 meters per sec. then u multiply 20 times 70 (the number of seconds it wus u get 1400 ft.
R = 2 x S R - 4 = a million + 3 x (S - 4) 2 x S - 4 = a million + 3 x (S - 4) 2 x S - 4 = a million + 3 x S - 3 x 4 upload 11 to the two components 2 x S + 7 = 3 x S subtract 2 x S from the two components 7 = S Sarah is 7 Ryan is 14 4 years in the past, Ryan became 10 and Sarah became 3 So, Ryan became a million greater beneficial than 3 x 3 Rex, in Indiana
I used proportions...
1/10 = 200/20
And then got 100 meters long.
