Kristin made a trip to the town hall and
back. The trip there took six hours and the
trip back took five hours. What was
Kristin's average speed on the trip there if
She averaged 30 mph on the return trip?

Step-by-step explanation:

Lets write down what we know.

The trip to the town hall took 6 hours.

The trip back took 5 hours.

She averaged 30mph on the trip back.

If we are supposed to find the average speed on the trip, we need to find the distance to the town hall.

Since we know that she went 30 miles every hour on the return trip, we can multiply 30 miles by the amount of hours it took her to calculate the distance.

30*5=150

The distance of her trip is 150 hours.

Now we need to calculate her average there.

If she took 6 hours to get there, we simply need to divide 150 by 6 to find her rate of speed.

150/6=25

Her average speed on the trip to the town hall was 25 miles per hour.

Hope this helps!

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
