Yes, because in order for 5/8 to have the same denominator as 11/20, you multiply 5 and 8 by 2.5, which equals 12.5/20.
5/8 is more than 11/20
If we find the lower common multiple of the denominators which is 160 then we can multiply the top numerators by the opposite denominators
5x20=100
11x8=88
We now have

The one on the left is simplified to 5/8 and the right is simplified to 11/20

All I could think is subtract and divide
<span>s = 60t - 3t^2
v = ds/dt = 60 - 6t
when it comes to rest, v = 0,
so t = 10 sec
now distance travelled = time taken x average velocity
= 10 x (60 + 0)/2
= 300 ft
