an aircraft travels for 5 hours a Travels at the speed of 210 km per hour for first two hours and at the speed of 240 km per hour for remaining time find the total distance travelled by the aircraft
distance travelled in first 2 hours=210*2=420 km
do do do remaining time = 3*240 =720 km
therefore distance travelled = 420 +720 = 1140 km.
do do do remaining time = 3*240 =720 km
therefore distance travelled = 420 +720 = 1140 km.
