Answer:

90 hour

Step-by-step explanation:

300 minutes is for 1 school week

so if you multiply 300 minutes for 18 weeks it results as 5400 minutes.

300 × 18 = 5400 minutes

To get the number of hours you should divide 5400 minute by 60 minutes      ( which is one hour )

5400 ÷ 60 =. 90 hours

You spent a total of 90 hours studying math in 18 weeks.

If Samuel can type 40 words per minute, he can type 40m words in m minutes. So, the amount of minutes you're interested in is the solution of the equation

40m = 3.5 \times 10^5 \iff m = \dfrac{3.5 \times 10^5}{40} = \dfrac{3.5 \times 10^5}{4\cdot 10} = \dfrac{3.5}{4} \times 10^4 = 0.875\times 10^4 = 8750 minutes.

Since 8750/60 is 145 with reminder 50, Samuel can type the required amount of words in 145 hours and 50 minutes.
