Question

1 5.) Eva can finish sewing a bag in 3 1/2 hours. Edna can do the same task in only 2 1/3 hours. How fast can Edna sew? ​

Answer 1

Answer:

70 minutes or 1 hour 10 minutes

Step-by-step explanation:

3 1/2=3×60+1/2×60=210 minutes.( Eva)

2 1/3=2×60+1/3×60=120+20=140 min. (Edna)

difference= 210-140=70 minutes.fast edna than Eva

Answer 2

Given,

Eva can finish sewing a bag in = 3½ hours

Edna can do the same task in = 2⅓ hours

To find,

How fast can Edna sew?

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

Eva can sew the bag in = 3½ hours = ⁷/₂ hours

Edna can sew the bag in = 2⅓ hours = ⁷/₃ hours

Edna can sew faster by :

= Eva's required time - Edna's required time

= (⁷/₂ -⁷/₃) hours

= (21-14)/6 hours

= ⁷/₆ hours

= 1⅙ hours

(This will be considered as the final result.)

Hence, Edna can sew faster than Eva by 1⅙ hour.
