If it takes 5 people 16 minutes to solve 10 problems, how many minutes will it take 8 people to solve 15 problems


Sagot :

Answer:please check 17.06667

Step-by-step explanation:

5person = 16 minutes x 10problems

= 5x = 16y(10z)

= 5x/16y(10z)

8person = y? x 15problems

= 8x = y?(15z)

=8x/?y(15z)

Cross multiply

8x(16y)(10z) = 5x(?y)(15z)

Transpose

8x(16y)(10z)/5x(15z)=(?y)

Solve for y

80xz(16y)/75xz=?y

1.06667(16y)=?y

Y=17.06667
