3 4/5 is the answer also the three is the whole number
Okay. To find the speed in meters, do 75 * 1,000. because 1,000 meters = 1 kilometer. 75 * 1,000 is 75,000. The speed is 75,000 meters an hour. But, it asks for meters per second and there are 3,600 seconds in one hour. To find this, we have to do division. 75,000/3,600 is 20.8 when rounded to the nearest tenth. The car goes about 20.8 meters per second.
Step by step explanation:
You first subtract z on both sides of the equal sign
ax-bx=(z-y)
Since a and b both have a "x" you can subtract them
(a-b)x=(z-y)
then you divide "x" on both sides of the equal sign
d =st
distance = speed * time
10 = 4.5 * t
divide each side by 4.5
10/4.5 = t
100/45 = t (can't have a decimal in a fraction so I multiply by 10/10)
divide top and bottom by 5
20/9
2 and 2/9 hours
to get minutes multiply 2/9 by 60
2/9 * 60
120/9
13 3/9
13 1/3 minutes
2 hours 13 1/3 minutes
to the nearest minutes
2 hours 13 minutes
