Answer:
The answer is 5/8
Step-by-step explanation:
Step 1 : Convert both fractions so they have the same denominator (bottom number in the fraction.) 
1/4 = 2/8
So now were dealing with : 
2/8 + 3/8 = ?
Step 2 : Add the numerators together to get the numerator for our answer. 
2 + 3 = 5
When adding two fractions with the same denominator the denominator stays the same, so our answer is 5/8. 
Hope this helps, please mark brainliest. :) Have a nice day. 
 
        
                    
             
        
        
        
The movement of the minute hand is circular.
Tangence speed is V=2Rπ/T= 2*7*3.14/3600 inches/sec=0.012211 inches/sec
The path (distance) that minute hand past is D=V*t = 0.012211 * 5 min= 0.012211 * 300sec=>
D=3.663≈3.66 inches
Good luck!!!
