A military jet cruising at an altitude of 12.0km and speed of 1400./kmh burns fuel at the rate of 40.7/Lmin . How would you calculate the amount of fuel the jet consumes on a 1500.km mission?
To find:
the amount of fuel the jet consumes on a 1500.km mission.
solution:
time taken for 1500 km mission = time taken for 1400 km + time taken for 100 km
= 60 min + (60/14)
= 60+4.3
= 64.3 min time taken for 1500 km mission is 64.3 minutes.
as the missile consumes 40.7 litres of fuel per minute.
fuel consumed for 1500 km mission = 64.3*40.7
=2617 litres
hence the total amount of fuel consumed in 1500 km mission is 2617 litres.
