Answer:
150 m/min
Step-by-step explanation:
D = RT
330 = 2.2R
R = 330/2.2
R = 150 m/min.
Answer:
420 miles in 2 hours.
If it where to fly for 13 hours then you divide 420 by 2 which is 210. Multiply 210 by 13.
=2730 miles.
The rate of speed would be 420 divided by 2. This would equal 210 miles per hour.
