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
A difference of 840 degrees
800 - (-40) = 840
When removing a negative number from a positive number you get a positive
- + - = +
800 - (-40)

Remember; horizontal treads is known as run in steps.
Now, calculating the slope of the stairways.
Formula: 
Rise= 7.25 inch
Run= 7 inch.
Subtituting the value in the formula
Slope= 
(∵ Round to two decimal)
∴ Slope of stairways is 1.04.
