A group entered the musem at 3:30 and came out at 5:15 how lomh were they inside the museum

The group spent 1 hour and 45 minutes inside the Museum

Step-by-step explanation:

Here, given the time in which a group of people entered into a company and that time they got out, we want to know the number of minutes they spent inside the museum

Mathematically that would be;

5:15 - 3:30

3:30 - 4:30 is an hour, 4:30 to 5:30 is another one hour making 2, but only 15 minutes was spent before 5:30

So the time spent will be 2 hours - 15 minutes p 1 hour 45 minutes

d. is the correct answer

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
