Jessica rode 38 miles on a bus. The ride took 48 minutes. What was the average speed of the bus?

47.5 miles per hour

Step-by-step explanation:

Speed = distance / time

48 minutes = 0.8 hours

Speed = 38 / 0.8

= 47.5 miles per hour

ANSWER: 21.235 m/s

Step-by-step explanation:

Distance travelled: 38 miles, 61155.1 m(SI unit of speed or average speed is m/s so distance has to be in meters and time has to be in seconds)

Time taken:48 minutes, 48×60 seconds= 2880 seconds

Average speed= total distance by total time taken: 61155.1/ 2880= 21. 235 m/s

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
