1.5 miles to centimeters ​
Gemiola [76]

hi

1 mile is  1 609 meters.  (rounded).

As there is 100 centimeters in a meter, then

1 mile is  160 900 centimeter.  

Then 1.5 miles , is 1 mile + one half so :

160 900 + 160 900 /2 =  160 900 + 80 450

                                     =  241 350

1.5 mile is  241 350  centimeters.  

please note that the value of a mile was rounded.
