The river is moving at 5 miles per hour. The river is 500 meters wide. A person can swim 15 miles per hour. Calculate the time it takes for the person to swim across to a point on the bank exactly opposite to his starting position and then back. Then calculate the time it takes for a person to swim upstream for 500 meters and then downstream for 500 meters back to his original starting position. Are these two times the same

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.
