Answer:
276,000 kg per minute
Explanation:
From the question each booster burns 690,400 kg of propellant in 2.5 min.
To calculate the amount of propellant each booster burns in a minute, simply divide 690,400 kg by 2.5 min.
=276,160 kg/min or 276,160 kg per minute
thus for every 1 min, 276,160 kg of propellant is burnt by each booster.
