Question

Answer 1

To find the time when the rainstorm is over, we need to add the duration of the rainstorm to the starting time. The rainstorm lasted for 90 minutes, so we added 90 minutes to 4:15 p.m. which gives us 5:45 p.m.

Step-by-step explanation:

To find the time when the rainstorm is over, we need to add the duration of the rainstorm to the starting time. The rainstorm lasted for 90 minutes, so we need to add 90 minutes to 4:15 p.m. We can start by converting the starting time to minutes. 4:15 p.m. is the same as 4 hours and 15 minutes. To convert to minutes, we multiply 4 by 60 to get 240 minutes and then add 15 minutes to get a total of 255 minutes. Next, we add 90 minutes to 255 minutes. 255 + 90 = 345. This means that the rainstorm will be over 345 minutes after 4:15 p.m. To convert this back to hours and minutes, we divide 345 by 60. The quotient is the number of hours, and the remainder is the number of minutes. 345 divided by 60 is 5 with a remainder of 45, so the rainstorm will be over at 5:45 p.m.
