John swims 5/12 of a mile in 3/8 of an hour. What distance, in miles, does john swims in an hour? A.) 1 5/9
B.)15/96
C.)5/20
D.)1 5/12

1 1/9 miles

Step-by-step explanation:

If john swims 5/12 of a mile in 3/8 of an hour, then;

5/12 miles = 3/8 hours

TO get the number of miles he swims in an hour, we will say;

x miles = 1 hour

Equating both expressions

5/12 miles = 3/8 hours

x miles = 1 hour

Cross multiply

3/8 x = 5/12

3x/8 = 5/12

3x * 12 = 5 * 8

36x = 40

x = 40/36

x = 10/9

x = 1 1/9

The amount he swims in an hour is 1 1/9 miles

4x and 6y

im not sure though

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
