Answer:
51 minutes!
Step-by-step explanation:
<em>Hello there fellow human!</em>
First off, you convert kilometers to miles.
1 kilometer = 0.62 miles; therefore, 8 kilometers = 8*0.62 = 4.96 miles
Next, you determine how many minutes it takes for John to cover 1 mile
which is gotten by dividing 41 by 4;
41 / 4 = 10.25. So it takes 10.25 minutes to cover 1 mile. (minutes per mile)
Next, you multiply the number of minutes taken to cover <em>1 mile (10.25)</em> by <em>4.96 miles (8 kilometers)</em>, 10.25 * 4.96 = 50.84 minutes. Rounding that to the nearest minute, you get 51 minutes which make sense because the amount of time taken to cover 4 miles (41 minutes) will be shorter than the time taken to cover 4.96 miles (50.84 minutes) since 4 miles is smaller than 4.96 miles.

All calculations where done with a calculator. If you don't have that, you can always divide manually and convert to fraction.
