Question

40 workers can make a wall 2om high in 5 hours. How will workers takes to make a wall that is 35m high​

Answer 1

Answer:

35 meters

Step-by-step explanation:

Assuming the length of the wall is L and if 40 workers can make this 20m-high wall in 5 hours, we can derive that each worker can build 20L/(40*5)=L/10 in one hour.

If the wall is 35m high and assuming the length L is the same, then

35L/(25xL/10)= 35*10/25=14

It will 14 hours for 25 workers to make a wall that is 35 meters high

Answer 2

Step-by-step explanation:

40 workers can make 20Meter in 5 hours

35M ?

time required for 1m wall =5/20

=0.25hour

time required for 35m wall = 0.25x35

= 8.75 Hour
