Question 408943: If it takes 1 hour to build something. How long would it take if I sped it up by 10%?

You can put this solution on YOUR website!

if it takes 1+hour to build something, means the time t=1hour

sped it up by 10%, means 10% less time will be needed

so 10% of +1+hour+ is t1=%2810%2F100%291hour

t1=+0.1hour..........if you like to have it in a min, then t1=+%0D%0A%0D%0A0.1%2A60=6min


remember:
the 10% rule - i.e. never increase your distance or speed more than 10% in one week...:))
