1. Bruno uses a wheelbarrow to haul wood from his backyard to the back of his neighbor's house, located 1869 meters away. If he takes 6 breaks evenly when pushing the wheelbarrow the full distance, when does he take his first break?
2. Bruno has 20 pieces of wood to take, but he can only take 4 each time. What distance, in centimeters, will he travel to move all of the wood?

311.5 meters, 18690 meters

Step-by-step explanation:

first question you dicide 1869/6

second question you divide 20/4 to get five then multiply that by 1896 to get 9345, however you have to account for the trips backs you need to multiply it by two

1,  Breaks at 267m 534m, 801m, 1068m, 1335m, 1,602m. = 6 equal breaks. So his first break is 267, as this shows equal breaks for the first journey as asked in question.

2. 9,345m = 5 journeys with 4 pieces of wood. =934500cm

Double for return is more likely answer Return is = 18,690m = 1869000cm  as they asked for cm and was total distance as asked in question to deliver 20 pieces of wood.

Step-by-step explanation:

This is easy instead of dividing by 6 we divide by 7

This is because the 6th break would not be at the start or at the end.

An example is with number 10 and 4 breaks

2,4,6,8 are the breaks if number was 10.

But if 10 asked for 5 breaks it would go decimal and divide by 6 which is one more than 5.

So the answer to 1) is 1869/7 = 267m, (+267) 534m, (+267), 801m, (+267)1068m, (+267)1335m (+267) 1602 metres.

Here he still walks for another 267 minutes and finishes meaning he had 6 equal breaks before hand, before he finishes the journey with the wheelbarrow.

Answer 2) We divide 20/4 = 5 then multiply 1869 x 5 to equal the 4 pieces of wood x 5 times. We find 1869 x 5 =   9345

Note you would have to show long division ie) 9 x 5 under each other as long division workings, note is the only product that you do not 'add a zero to' as its tens, so that when you multiply out 5 x 6 = 5x 6 as a zero is added to make 5 x 60 below that you get answer 300 and 9 x 5 is above is showing 45 and continue with the hundred and thousand product underneath until you get to 9345.

Then as it is a return journey we take 9,345 x 2 and say return journey = 18,690m

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

it would take 7/10 of an hour too fill the pool.
