Op MfM Breintyd kom ons agter dat meer mense begin saam kopkrap. Vir dié wat al ses weke lank saam dink, word die uitdagings nou al makliker. Wys jou net – enigeen kan met oefening al beter leer dink. Ons breine maak letterlik nuwe verbindings as ons ’n probleem in die oë kyk!
On MfM Braintime we notice that more and more people are joining us to scratch heads. Those who have been thinking along for the past six weeks are starting to say the problems are easier. It just shows you – with effort and practise anyone can learn to think better. Our brains literally make new connections if we face a challenge!
1. ’n Reghoekige kombuistafel is drie keer so lank as wat dit breed is. As dit 3 m korter en 3 m breër was, sou dit ’n vierkant wees. Hoe lank is die tafel? A rectangular kitchen table is three times as long as it is wide. If it were 3 m shorter and 3 m wider, it would be a square. How long is the table?2.
2. Die pakhuis was vol, toe laat Yolande ’n vrag bokse buite opstapel. Die stapel bokse was 6 m hoog, 10 m breed en 8 m lank. Yolanda benodig nou ’n reghoekige seil om die bokse teen die weer te beskerm. Watter grootte seil sal die stapel presies bedek? Yolanda found that the warehouse was full, so she stacked a truckload of boxes outside. The stack was 6 m high, 10 m wide, and 8 m long. Yolanda now needs a rectangular tarp (sheet) to cover the boxes for protection. What size tarp would cover the stack exactly?
3. Peter, Tom, Debbie en Robert staan in ’n ry by ’n toonbank in die Poskantoor. As Peter loop, is Tom in die tweede plek. As Debbie loop, is Peter voor in die ry. Wie is vierde in die ry?Peter, Tom, Debbie and Robert are standing in a queue at the Post Office counter. If Peter leaves, Tom is in the second place. If Debbie leaves, Peter is first in the queue. Who is fourth in the queue?
