Brazil
Brazil is, quite simply, the largest coffee producer in the world.
66.64 km
This can be written as 16 km/min.
Now, 1 km/min = 60 km/hr. Therefore, 16 km/min =
16*60= 960 km/hr.
Distance travelled by the aircraft is 800 km.
Therefore, time taken will be Distance ÷ Speed.
=> Time = 800/960 = 0.833333 hours.
Now, speed of the car is 80 km/h. distance travelled by the car in 0.833 hours—
Distance = Speed * Time.
=>Distance = 80 * 0.833 = 66.64kms.
Therefore, the car travels 66.64 km , when the aircraft traveled 800 km.
