Let's say Miles Carlos drove = x and taook time = t1
Miles <span>Maria drove = y and took time = t2
But the total mile both drove = 233 and took time = 4.4 hrs
So , x + y = 233
t1 + t2 = 4.4
However, speed = distance / time
for Carlos, 55 = x / t1
for Maria, 50 = y / t2
</span><span>x + y = 233
</span><span>55 t1 + 50 t2 = 233
</span><span>t1 + t2 = 4.4
</span>50 t1 + 50 t2 = 220
5 t1 = 13
t1 = 2.6 hrs for Carlos
t2 = 1.8 hrs
Therefore Maria drove 4.4 hrs

<span>The
question here is why using either compatible numbers or rounding as a method
for estimation would be the same?
Well, we use rounding as a method of estimation to get a solution in a certain
equation faster yet the same.
For example, in the given equation we have 32 x 695
=> Instead of 32, we can use 30
=> instead of 695, we can use 700
=> 30 x 700
=> the answer is 21 000
Now, let’s multiply the exact number
=> 32 * 695
=> 22 240
Not, really exact yet close.
That’s how estimation works.
