Question

After learning how to fly, Wendy reduced her daily commute time by 75\%75%75, percent. Previously, her commute took mmm minutes.
Which of the following expressions could represent Wendy's commute time, in minutes, after she learned how to fly?
Choose 2 answers:

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

= $\frac{25m}{100}$

= $\frac{m}{4}$

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

Answer 2

Answer:

1/4m and also 0.25m

Step-by-step explanation:

Because 75% is equal to 3/4. The remaining part is 1/4. 1/4 is als equal to 25% or 0.25. Then you just need to multiply it with m to get her new commute time.
