Usain Bolt ran 400 meter at the same average speed that he can ran the 200 meter. How long would it take him to run 400 meters? round your answer to netherworld nearest hundredth of a second

however long it took him to run 200 meters x 2

Step-by-step explanation:

200 x 2 = 400

so

the ratio is 1:2

to keep this ratio you must multiply whatever he ran x 2 to get your answer

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.
