Answer:
See below.
Step-by-step explanation:
The train leaves station A at 13:44 and arrives at station B at 15:12.
Which means the train took 1 hour and 28 minutes to arrive at station B.
The train travels at 300 km/h. It took at least one hour, so the answer > 300 km.
Now, the remaining 28 minutes. We divide them by 60, as there’s 60 minutes in one hour and multiply by 300, as that’s how fast the train travels per hour.
28/60*300 = 140.
300 + 140 = 440.
The distance between the stations is 440 km.
Answer:
11
Step-by-step explanation:
You don't need the parenthesis, so you get:
2 5/8 + 4 8/17 + 9/17 + 3 3/8
You combine the integer values and get:
9 + 5/8 + 8/17 + 9/17 + 3/8
You combine the fractions with the denom. of 8 and do the same with those with the denom. of 17 and get:
9 + 8/8 + 17/17
You simplify:
9 + 1 + 1 =
11
So... we have two numbers
say "a" and "b"
one is larger than the other, let us say, "b" is larger than "a"
by how much?
well, "<span>eight more than three times"
three times the smaller is 3 * a, or 3a
eight more than that is 3a + 8
so b = 3a+ 8
the sum of both of them is 52
so, we know that
a + b = 52
run a substitution on "b" on the 2nd equation, and solve for "a"
once you find "a", plug it back in the 2nd equation, to get "b"
