Question

the space shuttle solid rocket boosters were pairs of rockets used during the first 2 min of flight. each booster burns 660,300 kg of propellant in 2.5 min. how much propellant (in kg) does each booster burn in 1 min?

Answer 1

The ratio given in the problem for each booster is 660300 Kg of propellant in 2.5 min. To find how much propellant does each burn in 1 minute we will divide this amount.

`\frac{660300\text{ kg}}{2.5\text{ min}}=\frac{264120\text{ kg}}{1\min }`

Each booster burns 264120 kg in 1 min.
