You ride your bike for a distance of 30km. you travel ata a speed of 0.75km/minute. how many minutes does it take

Distance for which the bike is ridden = 30 km
Speed at which the bike is driven = 0.75 km/minute
Let us assume the number of minutes taken to travel the distance of 30 km = x
Now we already know the formula of speed can be written as
Speed = Distance traveled/ Time taken
0.75 = 30/x
0.75x = 30
x = 30/0.75
  = 40 minutes
So the time taken for riding a distance of 30 km will be 40 minutes. I hope this procedure is simple enough for you to understand.

                 (30 km) x (1 minute / 0.75 km)

             =  (30 x 1 / 0.75)  (km/minute)

             =       40 minutes .

The math is correct, but I wonder about the real world.
I don't know much about competitive biking, but you've got
this dude pumping along at almost  25 mph for 40 minutes
solid.   Is this realistic ?

The best answer is (a) which is universal law is in effect at all times. it is constantly at play in everything we do and governs our lives. it is also important to note that universal law applies to not only everything on earth, but everything in the universe as well, which is another reason why it is in effect at all times.
