Answer:
11 3/4 laps
Step-by-step explanation:
Bijoy Kumar's laps + Arun Kumar's laps + Binod Chhetri's laps = total laps.
We do not now how many laps Binod Chhetri ran, so he is x in the equation, Bijoy ran 8 1/2, and Arun ran 13 1/4.
8 1/2 + 13 1/4 + x = 33 1/2 =>
17/2 + 53/4 + x = 67/2 =>
34/4 + 53/4 + x = 67/2 =>
x + 87/4 = 67/2 =>
x = 47/4 =>
x = 11 3/4
answer: 11 3/4 laps
I hope this helps!
