Question

Bob and Nina make dog leashes . Bob can make 7 leashes in 2 hours and nina can make 4 leashes in 1 hour enter an equation that can be used to find the number of hours it takes bob and Nina to make 60 leashes

Answer 1

Nina: 4 leashes X 15 hours = 60 leashes
Bob:  3.5 leashes X 17.1428571428 hours = 60 leashes
(Sorry I couldn't make a fraction out of 17.1428571428)

Answer 2

Answer:

Number of leashes Bob can make in 2 hours = 7

Number of leashes Bob can make in 1 hour = 7÷2 = 3.5

Let, Bob takes total x hours.

Number of leashes Nina can make in 1 hour = 4

Let, Nina takes total x hours.

∴  The equation that can be used to find the number of hours it takes bob and Nina to make 60 leashes is given by-

3.5x+4x = 60.

7.5x = 60

This equation can be used to find the number of hours taken by Bob and Nina by putting different values of x and y which satisfies above equation.
