Answer :

Jimmy ate 8 , 16 , 24 sandwiches in 1 , 2 and 3 hours respectively .

To find : the no . of sandwiches Jimmy eat in 1 hour , 2 hour and 3 hours .

Given : y = the no . of sandwiches Jimmy can eat

      x = no . of hours he take in eating

Relation : y = 8 x

( i ) No . of sandwiches eaten  by Jimmy in 1 hour

x = 1

y = ( 8 * 1 )

y = 8

( ii )   No . of sandwiches eaten  by Jimmy in 2 hours

x = 2

y = ( 8 * 2 )

y = 16

( iii ) No . of sandwiches eaten  by Jimmy in 3 hours

x = 3

y = ( 8 * 3 )

y = 24

Hence , Jimmy ate 8 , 16 , 24 sandwiches in 1 , 2 and 3 hours respectively .
