What time is it now

What time will it be in 1000 seconds

10:13

1min = 60s

60s x 10 = 600s

60s x 2 =120s x 3 = 360s

600s + 360s = 960s + 40s = 1000s + 10:13

It's 7km from Tim's house to where his grandma lives.

It's uphill on the way, so he can only travel at 14 kph but he can do 21 kph on the way back.

Tim leaves his house at 6pm.

How long can he stop a Grandma's house if wants to be home to watch his favourite TV at 7pm?

14 kph ÷ 2 = 7km

1h ÷ 2 = 30mins

21 kph ÷ 3 = 7

1h ÷ 3 = 20mins

30mins + 20mins = 50mins

1h - 50mins = 10mins

Tim can stay at Grandma's House for 10 mins until he has to go home.

In some parking buildings in the city, you can get 15 minutes of parking for 50c.

Nigel put $3.50 into the meter at 3:15pm.

At what time did the parking meter expire?

$3.50 to 350c

350c ÷ 50c = 7 x 15mins = 105mins

105mins to 1h 45mins

1h 45mins + 3:15pm = 5:00pm
