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

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
