Question

9. Aarushi is helping her father plant trees to create
a border around the backyard. Aarushi plants a
tree every 25 minutes and her father plants a tree
every 15 minutes. If they started together, how
long will it be before they would finish planting
a tree at the same time.​

Answer 1

Answer:

They would finish planting a tree at the same time after 75 minutes

Step-by-step explanation:

Time they would finish planting a tree at same time = LCM of 25 and 15

P.F. of 25= 5x5

P.F. of 15= 5x3

L.C.M.= 5x5x3 = 75
