Zero (0) degree, viewing from my phone (nokia touch light). Mathematically: A clock is a circle, therefore, total sum of angle is 360. A clock is made up of 12 hours, each hour equals 30 degrees. Between 12 to 1 hour inclusive, there is 5 lines, each line stands for 6 degrees. As a result of my phone (I can't view the picture), here are your possible answers. At hour 3 and mins 15 =0 degree. At hour "3.2" (the hour pointer is now at 16 lines) and mins 15 = 6 degrees. At hour "3.4" (the hour pointer is now at 17 lines) and mins 15 = 12 degrees. Note: Dont mind my touch light phone. Or better still, can you help to note where the hour pointer is pointing to(I can't view picture on my phone)? |

The angle between the hour hand and the minute hand is 7.5° Should I explain how I got that? |

thankyouJesus: Zero (0) degreeseconded... Since d time is 3:15 |

Use ur protractor measure am |

factorial1: The angle between the hour hand and the minute hand is 7.5°please do |
Re: Let Me Test And Which Nairalander Can Answer This Simple Math by Meestique: 9:35pm On Sep 08, 2014 |
padeolu: seconded... Since d time is 3:15I would av thirded... Except for the fact that the hour hand is no longer directly on 3 . It has moved some distance away. |

7.5degrees |
Re: Let Me Test And Which Nairalander Can Answer This Simple Math by Nobody: 9:55pm On Sep 08, 2014 |
7.5 degrees |
Re: Let Me Test And Which Nairalander Can Answer This Simple Math by yorex2011: 9:56pm On Sep 08, 2014 |
Since there are 5 markings between each clock number (each hr) means it moves 60/5= 12mins for each marking.. Since its 15mins past 3 means it has moved 15/60 times 5 which is 1.25 marking... Now each marking is 360/60 degrees =6degrees..there fore it has moved 6 *1.25 =7.5 degrees... Hence dats d difference between d two hands |

7.5○ 1.25/60 = ×/360 × = 1.25×360/60 = 7.5○ Prof. DickDastardly 1 Like |

padeolu: seconded... Since d time is 3:15Lol, remember you ain't concerned with the time. The major thing is the angle between them. |

where is the op... I need my price bro. Kudos to yorex2011, DickDastardly and topelouis. |

Less than 5-degree(maybe 4.12 deg). |

Re: Let Me Test And Which Nairalander Can Answer This Simple Math by Caseless2: 11:26pm On Sep 08, 2014 |
DonaldGenes:that quadrant has 90-deg and the minute hand is jst slightly above 3. So, what ar u saying? I'v used compass clinometer in my surveys and i knw what i'm saying. |

DonaldGenes:Lol... |
Re: Let Me Test And Which Nairalander Can Answer This Simple Math by TVTKOKO(m): 11:41pm On Sep 08, 2014 |
DonaldGenes:in my opinion, it's 3 degrees. Lemme xplain: The angle btw 12 and 3o'clock is 45 degree.and btw these 45 degrees,we hav 15 mins so,dividing 45 degrees by 15 mins we hav 3 degrees for each minute and it's so obvious we hav a min. Btw dem hope i'm correct |
