Astar cuibheasach agus luaths cuibheasach – duilgheadasan agus fuasglaidhean

Duilgheadasan Fuasglaidh ann an Gluasad Loidhneach - Astar cuibheasach agus luaths cuibheasach

1. Bidh càr a’ siubhal air rathad dìreach chun an ear airson 100 meatair ann an 4 diogan, agus an uairsin a’ dol chun an iar airson 50 meatair ann an 1 diog. Obraich a-mach an astar cuibheasach agus an luaths cuibheasach.

Solution

Astar = 100 meatair + 50 meatair = 150 meatair

Gluasad = 100 meatair – 50 meatair = 50 meatair, chun an ear.

Ùine a chaidh seachad = 4 diogan + 1 diog = 5 diogan.

Astar cuibheasach = Astar / ùine a chaidh seachad = 150 meatair / 5 diogan = 30 meatair/diog.

Astar cuibheasach = Gluasad / ùine a chaidh seachad = 50 meatair / 5 diogan = 10 meatairean/diog.

2. Bidh neach a’ coiseachd 4 meatairean an ear ann an 1 diog, agus an uairsin a’ coiseachd 3 meatairean gu tuath ann an 1 diog. Obraich a-mach an astar cuibheasach agus an luaths cuibheasach.

Solution

Astar = 4 meatair + 3 meatair = 7 meatair

Gluasad = = meatairean, chun an ear-thuath.

Ùine a chaidh seachad = 1 diog + 1 diog = 2 dhiog.

Astar cuibheasach = astar / ùine a chaidh seachad = 7 meatairean / 2 dhiog = 3.5 meatairean/diog

Astar cuibheasach = gluasad / ùine a chaidh seachad = 5 meatairean / 2 dhiog = 2.5 meatairean/diog

3. Bidh ruitheadair a’ siubhal timcheall slighe ceart-cheàrnach le fad = 50 meatair agus leud = 20 meatair. Às dèidh dha siubhal timcheall air an t-slighe cheart-cheàrnach dà uair, bidh an ruitheadair a’ tilleadh chun a’ phuing tòiseachaidh. Ma tha an ùine a chaidh seachad = 100 diogan, obraich a-mach an astar cuibheasach agus an luaths cuibheasach.

Solution

Cearcall-thomhas ceart-cheàrnach = 2(50 meatair) + 2(20 meatair) = 100 meatair + 40 meatair = 140 meatair.

A’ siubhal timcheall ceart-cheàrnach 2 uair = 2(140 meatair) = 280 meatair.

Astar = 280 meatair.

Gluasad = 0 meatairean . ( ruitheadair air ais chun a' phuing tòiseachaidh)

Astar cuibheasach = astar / ùine a chaidh seachad = 280 meatairean / 100 diogan = 2.8 meatairean/diog.

Astar cuibheasach = gluasad / ùine a chaidh seachad = 0 / 100 diogan = 0.
