how do you solve 45 min/2 mi=?h/1 mi
If you go 2 miles in 3/4 hour, you go 1 mile in 3/8 hour (or 22.5 minutes).
3/8 hour
To solve the equation (45 min / 2 mi) = (x h / 1 mi), where x represents the unknown number of hours, you can follow these steps:
Step 1: Convert minutes to hours (since the units need to match for both sides of the equation). There are 60 minutes in 1 hour, so:
45 min = 45 min * (1 hr / 60 min) = 0.75 hr
Step 2: Substitute the values into the equation:
(0.75 hr / 2 mi) = (x h / 1 mi)
Step 3: Cross-multiply to solve for x:
0.75 hr * 1 mi = 2 mi * x h
0.75 mi-hr = 2x mi-hr
Step 4: Divide both sides of the equation by 2 to solve for x:
(0.75 mi-hr) / 2 = (2x mi-hr) / 2
0.375 mi-hr = x mi-hr
Therefore, the solution is x = 0.375 mi-hr.
