Term 1 Holiday maths.

Problem solving

1. Moana set her digital watch at 13:00:00 on the last day of April.

Unfortunately the watch loses 11 seconds a day.

What is the time on Moana’s watch when it is 13:00:00 on the last day of May?

There are 31 days in may. 31 x 11 = 341

If you convert 341 into minutes it would be 5 minutes and 41 seconds

Then subtract 5 mins and 41 secs from 13:00:00 which is….

12:54:19

2. In parking meters downtown, you can get 15 minutes parking for 50c.

Dad put $3.50 into the parking meter at 3.15pm.

5 o’clock

(7 groups of 50’s in 3.50)

15 x 7 = 105

105 is 1 hour and 45 mins

3.15 + 1 hour and 45 mins = 5.00pm

At what time did the parking meter expire?
