The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.

<h3>what is speed?</h3>

Speed is the time rate at which an object is moving along a path

Let the speed of southbound train is x miles/hour

so, northbound train has speed of x+10 miles/hour.

then, Speed of both train = Total distance/ total time

(x+10+x)=210/5

2x+10= 210/5

2x+10= 42

2x= 32

x= 16 miles per hour (southbound train)

northbound train:  16+10=26 miles per hour

This is all it gave me 6 C 2 = a0
frozen [14]

Answer:

\binom{6}{2} = a_{0}=15

Step-by-step explanation:

\binom{6}{2} = a_{0}

\binom{n}{r} =\frac{n!}{r!\times(n-r)!}

It is representing a combination form where, n is number of items we have and r is the number of items we choose from n

Here, n = 6 , r = 2

\binom{6}{2} =\frac{6!}{2!\times(6-2)!}

==\frac{6!}{2!\times(4)!}

n!=n\times(n-1)\times(n-2)\times(n-3).....\times3\times2\times1

=\frac{6\times5\times4!}{2\times(4)!}

=\frac{6\times5}{2}

={3\times5}

={15}=a_0

Thus, \binom{6}{2} = a_{0}=15
