Terry drove 310 miles in 5 hours at a constant speed. how long would it take him to drive 403 miles at the same speed

Take 310 and divide it by 5 to get Miles per Hour then divide 403 by the number you found(should be 62) to get the amount of hours need to travel 403 miles. So altogether you do 310 divided by 5=62 then 403 divided by 62=6.5 hours to travel 403 miles.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

Ithink it's b sorry if i'm wrong
