Sally swam a total distance of 3 and 1 over 2 miles during the months of november and december. if sally only swam 1 over 4 of a mile every day, which expression shows the number of days she went swimming? ?

3 and 1 over 2 ⋅ 1 over 4
3 and 1 over 2 ÷ 1 over 4
3 and 1 over 2 + 1 over 4
3 and 1 over 2 – 1 over 4

3 and 1 over 2 ÷ 1 over 4

Step-by-step explanation:

Given,

Total distance Sally swam = miles,

Also, the distance she swims each day = miles,

Hence, the number of days she went swimming =

= 3 and 1 over 2 ÷ 1 over 4

Second option is correct.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
