*Hey :)
-Hi
*Guess what? Yesterday I ran 2 miles!
-Really? How much would that be in kilometers?
*One mile is 1.61 kilometers so you have to multiply, 2 × 1.61 and that is 3.22, so I ran 3.22 kilometers yesterday
-Woah that's a lot! I bet you must have drank a lot of water
*Omg Yes! I had a bottle of water of 5 gallons and I drank it all!
-5 gallons it's equal to 18,95 liters, right?
*Yes it is!
-Well, I have to go now, but next time we should go running together. Bye!
*Ok bye
