Answer :

You, Newton, and Descartes walk dogs to earn spending money this summer. You spend 2 times as many minutes walking dogs as Newton. Descartes spends 3 times as many minutes walking dogs as Newton. You, Newton, and Descartes spend 3,030 minutes walking.dogs altogether. How many minutes does Newton walk dogs? ​

Let

x -----> minutes does Newton walk dogs

y ----> minutes does Descartes walk dogs

z ----> minutes does you walk dogs

so

z=2x ------> equation A

y=3x ------> equation B

x+y+z=3,030 ------> equation C

substitute equation A and equation B in equation C

x+(3x)+(2x)=3,030

solve for x

6x=3,030

x=505 minutes

therefore

the answer is

Newton walk dogs 505 minutes
