Let's look at the difference in speed between the two: it's 39-15.6=23.4 km/h
(we can just subtract this because they are traveling in the same direction) - this means that it's as if the slower train (the freight) was in place and the passenger train was traveling at 23.4 km/h
No, the freighter left 3.9 hours earlier, during which it traveled
15.6*3.9=60.84 km
So they will meet when the passenger train will catch up on those 60.84 km.
It does it with 23.4 km/h so it will need:
So the freighter will be travellinf for 2.6 more hours than the other train - a total of (2.6+3.9=6.5) 6.5 hours!
In economics, the formula relating the future value (F)
and present value (P) at simple interest (i) and number of years (n) is:
F = P (1 + i)^n
Since we are to find for n, let us rewrite this equation:
(1 + i)^n = F / P
Taking the log of both sides:
n log (1 + i) = log (F / P)
n = log (F / P) / log (1 + i)
Substituting the given values:
n = log (2,340 / 1,800) / log (1 + 0.05)
n = log (1.3) / log (1.05)
n = 5.38

Answer:
61 miles in one hour
Step-by-step explanation:
366/6=
6*6=36
366/6=06
6*1=6
366/6=061 miles per hour
Answer:
3
Step-by-step explanation:
We need to find the lowest common multiple of 8 and 12.
Reminder that the LCM is the lowest number that divides evenly with both of the given numbers.
We can make a chart and see that:
Multiples of 8: 8, 16, 24, 32
Multiples of 12: 12, 24...wait! We have a match with 24!
Therefore, there will be 24 more games until both events will occur.
