Speed is distance over time. There’s no distance in the question and the time is 1 hr 30 mins hence 1.5 hours.
Simple just subtract and u get-74.85
Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j

Answer:
6 team members
Step-by-step explanation:
We know that 2 team members can solve 13 problems in an hour. So, all you have to do is find what 195÷13 is, and multiply that by 2.
195÷13= 315
15*2= 30
And we have our answer!
I hope this helps! If it did, it would mean a lot to me if you could mark me brainliest :D
Have a nice day!
