Answer:
3/4 of a hour
Step-by-step explanation:
2 miles = 0.5 hours
Divide by 2
1 mile = 0.25 hours
Multiply by 3
3 mile = 0.75 hours
Answer:
45 minutes or .75 of an hour or 3/4 of an hour
Step-by-step explanation:
if you walk 2 miles in a half-hour (30 minutes) , how long will it take to walk 3 miles. Well the answer is simple, we need to use proportions to solve it though. For example:
[tex]\frac{miles}{hours}[/tex] = [tex]\frac{2}{.5}[/tex]
therefore, half of .5 is .25
so for someone to complete 1 mile, it takes .25 of an hour. .25 of an hour is 15 minutes. Therefore, the correct simplified proportion is : [tex]\frac{1}{.25}[/tex]
Now we need to find out what the denominator (bottom number/time) would be when the numerator (top number of the fraction) is =3.
Since we have the simplified version as a 1, we can just multiply .25 by 3 which is .75, and .75 of an hour is 45 minutes. Therefore the answer is 45 minutes.
