Welcome back to #MondayMath once again.
For a few months now, we have been posing Math questions every Monday on our Facebook page. These are questions that our students also encounter in Mathematics classes at B.D. Somani.
Last week, we asked you to decode some pictures. This week, we take a look at the Winter Olympics.
Tiara and her dad were in Calgary watching five Canadian teams try to qualify for her favourite Olympic event – the four-man bobsled. On each team a driver sits in front, followed by two teammates and the brakeman in the back.
The numbers 1 through 20 were assigned to the 20 athletes. The drivers wore numbers 1, 2, 3, 4, and 5.
Before the race Tiara studied the teams. Drivers 2, 3, and 4 were riding with brakemen 18, 15, and 20 respectively in three of the sleds. In another sled were 6 and 12, and in the remaining sled were 10 and 17.
Suddenly Tiara announced to her dad, “Wow! If you add up the four numbers on each team, all five sums are the same!”
- What was the sum of the numbers for each team?
- Who were driver number 1’s teammates?
