Answer:
- Calculate the time (in minutes) that it would take for the jet to cover the distance at the given speed.
- Multiply the time with the rate of burning of fuel by the jet.
Step-by-step explanation:
A military jet cruising at an altitude of 12.0 km and speed of 1200 km/h burns fuel at the rate of 80.1 L/min. How would you calculate the amount of fuel the jet consumes on a 750 km mission?
In order to calculate the amount of fuel that would be consumed, first, there is a need to find the time it will take to complete the 750 km mission.
Recall that: speed = distance/time, at a speed of 1200 km/h, the time taken to cover a distance of 750 km would be;
time = distance/speed
= 750/1200 = 0.625 h
The rate of fuel burning is 80.1 Liters in a minute, there are 60 minutes in 1 hr;
1 hr = 60 minutes
0.625 h = 0.625 x 60 = 37.5 minutes
It takes 37.5 minutes to cover 750 km and the fuel burning rate is 80.1 liters per minute, hence, the amount of fuel consumed by the jet would be;
80.1 x 37.5 = 3000 liters
