I believe it is 35!
I hope this helps you, and don't forget to give this answer brainliest if it really helped!
Use proportions
78cm / 38cm =. X/290cm
Remember it says 29m so it is 290 in cm
So let's say that 32 letters will be the numerator and 4 minutes will be the denominator so the fraction would belayed out like this --> 32/4
Now to reduce this to lowest terms, you would just divide both of the numbers by 4 to get 8 letters every 1 minutes or 8/1
I hope this helps!
