You walked a dog 0.75 miles. how many kilometers did you walk? (1 mile equals about 1.61 km)

A. 1.02 km

B. 0.88 km

C. 0.47 km

D. 1.21 km

What we have so far:

*Distance you walked the dog = 0.75 miles

*Conversion: 1 mile is approximately 1.61 kilometers

What we are trying to find:

*Distance you walked the dog in kilometers.

To solve this problem we must:

*We must employ conversion first.

Step 1) 0.75miles x 1.61km/1miles < - - - Multiplication will be employed.

Step 2) 0.75 x 1.61/1 (km) < - - - notice that we deleted the unit "miles". We did that to make sure that the result will be in kilometers (km).

Step 3) 0.75 x 1.61 (km) < - - - Since we are already done with the conversion process, we now have to multiply the distance and the conversion factor.

Step 4) 1.2075km < - - - Raw result.

Step 5) Rounding it up to two decimal places: 1.21km

Therefore, the correct answer is: D. 1.21km
