0.13 mph
3.6 mph
0.28 mph
7.7 mph

5. Mrs. Patil travels from her home to work in 0.25 hours. The direct distance between her home and work is 8.0 miles. If Mrs. Patil travels 12.4 miles from her home to her job, what is her average velocity?
32 mi/h
50 mi/h***(my answer)
16 mi/h
30 mi/h

Please help with these two!

Answer 1

Answer 4

Average velocity is given as

Average Velocity = total distance / total time

`v = (d)/(t)`

now it is given that

d = 12.2 miles

t = 3.4 hours

now we will use the above equation

`v = (12.2)/(3.4)`

`v = 3.6 mi/h`

So average speed is 3.6 mph

Answer 5

Average velocity is given as

Average velocity = total displacement / total time

now given that

total displacement = 8 miles

total time taken = 0.25 hours

now by above formula

`v = (8)/(0.25)`

`v = 32 mi/h`

So average velocity is 32 mph
