Question

The space shuttle's solid rocket boosters were pairs of rockets used during the first 2 min of powered flight. Each booster burns 690,400 kg of propellant in 2.5 min. How much propellant (in kg) does each booster burn in 1 min?

Answer 1

276,000 kg per minute

Step-by-step 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.
