My Answer is:

1/4*80=60

1/4*60=45

1/4*45=33.75

1/4*33.75=25.31 for the speed

Or I need to use some kind of formula? Please help me.

**MathMat**, Monday, May 6, 2013 at 10:17amI am not sure what the formula is, but I can tell you that 1/4 multiplied by 80 is not 60. It would be 20. 60 is 3/4 of 80.
