Question

After learning how to fly, wendy reduced her daily commute time by 75%, percent. Previously, her commute took m minutes.

Answer 1

`(1)/(4)m`

Explanation:

suppose m represents 100% of the time it took for wendy to travel

if she reduces her travel time by 75%, to find the amount of time she currently takes we subtract the original time minus the time saved to find the time she is currently traveling

`100-75=25`

let's assume that 100 is equal to 1 now to find out how much 25 equals we apply a simple rule of three

`100 \longrightarrow 1\\25 \longrightarrow x\\x=(25)/(100) \\x= (1)/(4)`

Then 25% of the time (which is what she now takes to travel) is equivalent to 1/4 of the original time it took

then if it took m minutes now it will take
`(1)/(4) m`

Answer 2

Suppose Wendy has to travel from A to B.

Starting commute time = m minutes

Wendy started learning flying i.e other way of commuting

it reduces her commute time by 75%

A.T.Q

now the new time i.e less time taken by Wendy to commute from A to B=

= m-75%of m

= m-
`(75* m)/(100)`

=
`(25* m)/(100)`

= m/4 Minutes

So,New commuting time for Wendy = m/4 Minutes
