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

Answer: $\$1100$

Step-by-step explanation:

Given

Principal amount is $P=\$4000$

Rate of interest $R=5\%$

Time period $T=5\ yr\ \text{and}\ \text{6 months}\equiv 5.5\ yr$

We know, Simple interest is

$\Rightarrow S.I.=\dfrac{P\times R\times T}{100}$

Putting values

$\Rightarrow S.I.=\dfrac{4000\times 5\times 5.5}{100}=\$1100$

Sara gets $\$1100$ after 5 years and 6 months
