Leila runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?

4.2 miles

Leila running rate = 6 miles/ 50 minutes = 3/25 mi per minute

Rate = distance/ time

3/25 = distance / 35

3/25 * 35 = distance

4.2 = distance

so she can run 4.2 miles

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.
