In a 3 hour examination of 350 questions, there are 50 mathematics problems. if twice as much time should be allowed for each mathematics problem as for each of the other questions, how many minutes should be spent on the mathematics problems?

7 minutes

Step-by-step explanation:

350/50=7

3*2.3333=7

You have to use the theorem. which is A^2+B^2=c^2... so do 12x12 and 6x6 and add the answer of both together. then put c^2 after an equal sign. then add the sums together and then square root the sum and the c^2. so you’re answer woild be closer to 72:)
