At a brick laying contest, each layer of bricks is expected to be 5/8 of an inch tall. three contestants recorded the fraction of layers of brick they placed and the time it took them to place the bricks in the table below. brick layer|fraction of layers|num. of minutes
zeke| 3/5 | 40
——-
xavier| 4/5 | 80
———
melanie| 6/5 | 55

calculate each contestants unit rate in inches per hour.

zekes unit rate was __ inch(es) per hour
melanie’s unit rate was __ inch(es) per hour
zekes unit rate was __ inch(es) per hour greater than xavier’s unit rate.

p. s. whoever answers this, i hope that the makeshift table i put makes sense to you, i’m so confused and i don’t have enough storage on my phone to download the app :/
