Atrain travels 204 miles in 4 hours. if it continues to travel at the same rate how many miles will it travel in 7 1/2 hours

Hello!

Right now, we know that the train has travelled 204 miles in exactly four hours. In order to find how many miles the train travels per hour, we can divide 204 by 4:

204/4 = 51

The train is traveling 51 miles per hour. The train still needs to travel 3 1/2 more hours. To find how many miles it will travel, we can multiply 51 by 3, and add 51/2.

51 x 3 = 153

51/2 = 25.5

153 + 25.5 = 178.5

The train travels 178.5 miles in the additional 3 1/2 hours. Now, we will add this number to the number of miles that the train has already travelled in four hours:

178.5 + 204 = 382.5

The train will travel 382.5 miles in 7 1/2 hours.

I hope this helps you! Have a lovely day!

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
