If beaver family one can cut down and 20" tree in 15 minutes and family two can cut down a tree 3 times the size in twice as long how long will it take the second beaver family to cut down a 20" tree

Respuesta :

Answer:

10 minutes

Step-by-step explanation:

Beaver family 2 can cut down 60'' (20 x 3) tree in 30 (15 x 2) minutes

In one minute, beaver family 2 would cut down 60/30 = 2'' tree

time to cut down 20'' tree = 20/2 = 10 minutes
