11) 88140 divided by 4520 = 19.5 meaning you would need 20 fire extinguishers
0.8 = 1.6. this is because the model is shaded as 1.6 but 0.8 has been shown by underlining it underneath the model.
Car 1. (40 kph):
40 kph = 40,000 km per hour
Car 2. (15 mps)
15 mps x 60 (to get one minute) = 900 mpm
900 meter per minute
900 x 60 = 54,000 km
Therefore, car 2 is faster since it drives at 54km per hour and car 1 only travels at 40km per hour.
Also, you decide which car you want to choose.
Hope this helps! Have a great day.
First step
12 x 1.3
Second step
15.6 x 7.5
The answer is 117 :)
So if the earth goes 18 miles per second you would multiply 18 and 60 since 60 seconds are in a minute. And that is 1,080 miles in a minute then times that by 5 and your answer is 5,400 miles in 5 minutes.
