Answer:
270
Step-by-step explanation:
becasue 100 percent of 90 would be 90

so multiply

300=x+1.9x
I got this by dividing the problem into two parts x[the speed of the first half] plus 1.9x [the speed of the second half increased by 1.9] both of those together should give you 300.
I went further and solved this...If you placed 103.5 into this problem for x you should get 300.15!
X^2+4x+4 and there is no remainder
