A dozen is 12
multiply 5 * 12 = 60
multiply (3/4) * 12 = 9
Then add together
60 + 9 = 69
C. 1 minute per 60 seconds.
4(x-1)=-4+4x
4x-4=-4+4x
-4x -4x
-4=-4
Not sure what the problem was asking, but it’s solvable!
Distance=speed times time
distance/time=speed
distance=538
time=9 and 15mins
60mins=1hr
15/60=1/4=0.25
time=9.25hr
distance/time=538/9.25=58.162mph
about 58mph
