So you know distance=rate(time). You could use the equation 40(x)+20(2-x)=54. After simplifying, you get x=7/10 or 0.7 hrs. Btw, x represents time downhill, while 2-x represents time on flat terrain since the total is 2. If you don't want to read all that, the answer is 0.7 hrs.

An established company started with 147 employees. After 10 years in business, they now have 283 employees. What is the percent
xeze [42]
So, Increase = New Number - Original Number. Therefore, Increase = 283 - 147 which equals 136.
136 = 283 - 147.
Then you want to divide the increase by the original number and multiply the answer by 100.
136/147 = 0.92
0.92 * 100 = 92.

Final Answer: The employee count has increased by 92%. I hope this helps.
