Andy drove 840 miles in 12 hours. How far could he drive in 3 hours?​

Sagot :

To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.
So in order to solve this problem we first have to divided
840 divided by 12 is 70
So that means that Andy drives 70 miles per hour
We need to find out how much miles Andy drives in 3 hours so we have to multiply the number of miles he drives per hour by 3
70*3=210
Therefore,Andy drives 210 miles in 3 hours
