Alright, so he went the same distance there and back, but at different speeds
hmm
d=st
d/s=t
total time is 9.5hr
alright
so distance there=distance back we will call both of them d
so
speed there is 10
speed back is 9
total time is 9.5
so
d/sthere+d/sback=totaltime
d/10+d/9=9.5
times both sides by 90
9d+10d=855
19d=855
divide both sides by 19
d=45
he can ride 45mi away

3x = 33
x = 11
D. The "a" value stretches the function vertically by a factor of absolute value of a.
10.2=10.20
So, 10.2 is bigger than 10.02
