Question

After learning how to fly, Wendy reduced her daily commute time by 75% Previously, her commute took m minutes. Which of the following expressions could represent Wendy's commute time, in minutes, after she learned how to fly? Help guys i don't know

Answer 1

Given:

(i) Wendy reduced her daily commute time by 75% by learning how to fly.

(ii) Previously, it took her 'm' minutes to commute.

To find:

(i) Wendy's commute time in minutes after she learned how to fly.

Solution:

Given that earlier it took Wendy 'm' minutes to commute.

After learning how to to fly, the commute time reduced by 75%.

So, time taken now = (100-75)% of previous time

= 25% of 'm' minutes

= \frac{25m}{100}

100

25m

= \frac{m}{4}

4

m

So, the time taken by Wendy now is \frac{m}{4}

4

m

minutes.
