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.
