Answer:
See below
Step-by-step explanation:
From noon to 1500 is three hours
train A then travels <u> 3x</u> where x = speed in km/hr
train B only travels for 2.45 hours and covers
<u> 2.45 ( x + 15) </u> where x + 15 is its speed in km/hr
these two values sum to the 300 km distance
3x + 2.45 ( x + 15) = 300
3x + 2.45 x + 36.75 = 300
x = 48.3 km/hr x+15= 63.3 km / hr

Answer:
Option A. 17.6%
Step-by-step explanation:
Since it is given that stems are in whole percent and leaves are tenths of percent which means if we take the first steam value of 5 7;
it means that 5 is whole percent and 7 will be written as 
= 0.7 percent which as a whole indicate that the first stem leaf represent 5.7% of residents aged 65 and over.
Now the highest percent of older residents for Florida will be the last stem leaf in the data given as 17 + 0.6 will represent 17.6% which is the highest among all others.
5.7% is the lowest of them all and there is no value as of 176% in the given stem leaf plot data.
Therefore option A id correct with 17.6% percent as of Florida.
