On Saturday, Conner drives 62 1/4 miles each hour. If he travels for 4 hours, how many miles does he travel altogether? please h

Taya2010 [7]

You would multiply 62 1/4 and 4. Which you cant do that so you would have to make it into a inproper fraction so that will be 249/4 times 4/1 then you can multiply which your answer would be 996 /4 and then in simplest form would be 249/1= 249
