If you have to convert to Joules/second

the result will be 35000*1000/ (.250*60) = 2333333.333

If you have to round it to two decimal places, check the digit in the 3rd decimal place.

The number is 3 which is less than 5.

so just ignore it. The result will be  just 2333333.33

Note: suppose you got the result 2333333.335 in the calculator and you have to round it to two decimal places, check the digit in the 3rd decimal place.The number is 5 which is greater than or equal to 5.

so add 1 to the digit in the 2nd decimal place.

so the result will be 2333333.34

Please let me know if you need any clarification. I'm always happy to answer your questions.
