If a person walks 1/2 mile in 1/4 hour, how far does that person walk in 1 3/4 hours at that rate?
Answer:
3 1/2 miles
Step-by-step explanation:
We can use a ratio to solve
1/2 mile x miles
----------------= ---------------
1/4 hour 1 3/4 hours
Changing to improper fractions
1/2 mile x miles
----------------= ---------------
1/4 hour 7/4 hours
Using cross products
1/2 * 7/4 = 1/4x
7/8 = 1/4x
Multiply each side by 4
7/2 = x
Changing back to a mixed number
3 1/2 =x
