Qhov nruab nrab ntawm qhov ceev thiab qhov nruab nrab ntawm qhov ceev - cov teeb meem thiab cov kev daws teeb meem

Tau daws cov teeb meem hauv kev txav mus los ncaj - qhov nruab nrab ntawm qhov ceev thiab qhov nruab nrab ntawm qhov ceev

1. Ib lub tsheb khiav raws txoj kev ncaj mus rau sab hnub tuaj li 100 meters hauv 4 vib nas this, ces mus rau sab hnub poob li 50 meters hauv 1 vib nas this. Txheeb xyuas qhov ceev nruab nrab thiab qhov ceev nruab nrab.

tshuaj

Qhov Nrug = 100 meters + 50 meters = 150 meters

Kev Hloov Chaw = 100 meters – 50 meters = 50 meters, mus rau sab hnub tuaj.

Lub sijhawm dhau mus = 4 vib nas this + 1 vib nas this = 5 vib nas this.

Qhov nruab nrab ntawm qhov ceev = Qhov deb / lub sijhawm dhau mus = 150 meters / 5 vib nas this = 30 meters/ib vib nas this.

Qhov nruab nrab ntawm qhov ceev = Kev hloov chaw / lub sijhawm dhau mus = 50 meters / 5 vib nas this = 10 meters / vib nas this.

2. Ib tug neeg taug kev 4 meters mus rau sab hnub tuaj hauv 1 vib nas this, tom qab ntawd taug kev 3 meters mus rau sab qaum teb hauv 1 vib nas this. Txheeb xyuas qhov ceev nruab nrab thiab qhov ceev nruab nrab.

tshuaj

Qhov Nrug = 4 meters + 3 meters = 7 meters

Kev Hloov Chaw = = meters, mus rau sab qaum teb sab hnub tuaj.

Lub sijhawm dhau mus = 1 vib nas this + 1 vib nas this = 2 vib nas this.

Qhov nruab nrab ceev = qhov deb / lub sijhawm dhau mus = 7 meters / 2 vib nas this = 3.5 meters / vib nas this

Qhov nruab nrab ntawm qhov ceev = kev hloov chaw / lub sijhawm dhau mus = 5 meters / 2 vib nas this = 2.5 meters/ib pliag

3. Ib tug neeg khiav ncig ib txoj kev plaub fab uas ntev = 50 meters thiab dav = 20 meters. Tom qab ncig ib txoj kev plaub fab ob zaug, tus neeg khiav rov qab mus rau qhov chaw pib. Yog tias lub sijhawm dhau mus = 100 vib nas this, txiav txim siab qhov nruab nrab ntawm qhov ceev thiab qhov nruab nrab ntawm qhov ceev.

tshuaj

Lub voj voog ntawm lub duab plaub fab = 2 (50 meters) + 2 (20 meters) = 100 meters + 40 meters = 140 meters.

Mus ncig lub duab plaub fab 2 zaug = 2(140 meters) = 280 meters.

Qhov deb = 280 meters.

Kev Hloov Chaw = 0 meters . ( khiav rov qab mus rau qhov chaw pib)

Qhov nruab nrab ntawm qhov ceev = qhov deb / lub sijhawm dhau mus = 280 meters / 100 vib nas this = 2.8 meters / vib nas this.

Qhov nruab nrab ntawm qhov ceev = kev hloov chaw / lub sijhawm dhau mus = 0 / 100 vib nas this = 0.
