Your voltmeter and your teacher are both right, but the water analogy of electricity can only go so far. One big drawback is that, unlike with water, there is no absolute voltage. .... Wherever you put the black lead is defined as "0V". .... flowing (i.e. the circuit is broken) you will not get this change in voltage.
Answer:
53.33 hours or 53 hours and 20 minutes.
Explanation:
Given, one travels at 45 miles/hr and another 30 miles/hour.
Let, the slower broom, S1 = 30t
According to the Question,
S1 + 800 = 45t....... (1)
S1 = 45t - 800......(2)
t is constant for because time is equal for both.
Now, putting (1) in equation (2),
30t = 45t - 800
30t - 45t = - 800
15t = 800
t = 53.33
So, the answer is 53.33 hours.
