All we have to do is subtract 8:25 by 7:35 to figure out the time kurt took to get to school, which would equal to 90 minutes. Then we have to subtract 8:30 by 7:55 to get the amount of time it took for Drew to get to school which is 75 minutes. We can see that Drew has the lowest number which means he got to school faster so last step is to subtract the two times 90-75 which equals to 15. Which means drew got to school 15 minutes faster.
First write nine ten thousands in standard form which is 90,000. Next divide 90,000 by 10 and you should get 9,000 by crossing out one zero in both numbers. To get 9,000 in unit form all you have to write is 9 thousands. And your answer is 9 thousands
