30 Days = 40 Cans
6 Days (30/5 Days) = 8 Cans (40/5 Cans)
5x - 10 <6x - 8
Collect the like terms
5x - 6x < -8 + 10
-x < 2
= x > -2
I’m not really sure if your equations is correct, but base on my calculations thats the answer. Hope this helps! :))
Distance = 15 km
time = 30 min
= 30/60 hrs
= 1/2 hr
speed = distance / time
= 15 / 1/2 (0.5)
= 30 km / hr
Therefore, speed of horse = 30 km / hr.
