Suzi began fishing at 10:50 A. M and fished until 11:30 James finished fishing at 11:45 A. M. He fished for the same length of time as Suzi. At what time James start fishing?

11 : 05 A.M.

Step-by-step explanation:

Given:

Suzi began fishing at 10:50 A.M and fished until 11:30.

James finished fishing at 11:45 A.M.

He fished for the same length of time as Suzi.

Question asked:

At what time James start fishing?

Solution:

First of all we will find how long Suzi fished and to find we will subtract when she began from when she finished fishing:-

Hour              Minutes

 11                         30  ( Taking 1 carry from hour, means 60 min)

- 10                        50  ( 60 + 30 = 90 min - 50 min = 40 min)

 0 hour                40 minutes  

( 11 hour - 1 hour = 10 hours, 1 hour carry given)

( 10 hours - 10 hours = 00 hours )

That means she fished 40 minutes and James also fished 40 minutes.

Now, to know, at what time James start fishing, we will subtract when he finished fishing from 40 minutes.

Hour              Minutes

 11                        45          

- 00                      40          

 11                       05  

Thus, James start fishing at 11 : 05 A.M.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
