tony walked 3.5 miles in 7/8 of an hour. at this rate, how many miles can tony walk in one hour?
3.5/(7/8) = x/1
Cross multiply and solve for x.
7/8x = 3.5
x = 3.5 / 0.875
x = 4 miles
To find out how many miles Tony can walk in one hour:
Step 1: Determine the distance Tony walked in 1 hour
Since Tony walked 3.5 miles in 7/8 of an hour, we need to find out how many miles he can walk in 1 hour.
Step 2: Divide the distance walked by the fraction of an hour
To calculate the number of miles Tony can walk in one hour, divide 3.5 miles by 7/8 of an hour.
3.5 miles ÷ (7/8) hour = 3.5 × (8/7) miles
Step 3: Perform the division
To simplify the calculation, convert the fraction 8/7 into a decimal.
3.5 × (8/7) miles = 3.5 × 1.14 miles
Step 4: Calculate the final answer
Multiply 3.5 by 1.14 to find out how many miles Tony can walk in one hour.
3.5 × 1.14 = 3.99 miles
Therefore, Tony can walk approximately 3.99 miles in one hour.
To find out how many miles Tony can walk in one hour at this rate, we can use the concept of unit rate. Unit rate refers to the rate at which something happens or is done in relation to a single unit of time, in this case, one hour.
Given that Tony walked 3.5 miles in 7/8 of an hour, we can set up a proportion to find the number of miles he can walk in one hour:
3.5 miles / (7/8) hour = x miles / 1 hour
To find x, the number of miles Tony can walk in one hour, we can cross-multiply and solve for x:
3.5 miles * 1 hour = x miles * (7/8) hour
3.5 = (7x) / 8
Next, we can multiply both sides of the equation by 8 to eliminate the fraction:
3.5 * 8 = 7x
28 = 7x
Finally, divide both sides of the equation by 7 to isolate x:
28 / 7 = x
4 = x
Therefore, Tony can walk 4 miles in one hour at this rate.
