Time measurement answers: exercises 1 to 10

Exercise 1 – Read the clock (1)

The hour hand is just past the 8, so the hour is 8. The minute hand is 1 mark past the 3: \(3 \times 5 = 15\) and \(15 + 1 = 16\). The time is 8:16.

Exercise 2 – Read the clock (2)

The minute hand is 2 marks past the 10: \(10 \times 5 = 50\) and \(50 + 2 = 52\). The hour hand is close to 11 but has not reached it, so the hour is 10. The time is 10:52.

Exercise 3 – Write the time

14 minutes after 6 o’clock is 6:14. Evening is after noon, so the time is 6:14 P.M.

Exercise 4 – Minutes until the hour

From 52 minutes to 60 minutes: \(60 – 52 = 8\). There are 8 minutes until 4:00.

Exercise 5 – Elapsed time in one hour

Both times are in the same hour: \(45 – 10 = 35\). The elapsed time is 35 minutes.

Exercise 6 – Find the end time

5:20 plus 40 minutes: jump 40 minutes from 5:20 to reach 6:00 (20 + 40 = 60). Practice ends at 6:00.

Exercise 7 – Number line jumps

Jump from 10:15 to 11:00: 45 minutes. Jump from 11:00 to 11:05: 5 minutes. \(45 + 5 = 50\).

10:1511:0011:05+45 min+5 min
The elapsed time is 50 minutes.

Exercise 8 – Find the start time

Jump back 30 minutes to 8:00, then back 25 more minutes (\(30 + 25 = 55\)) to 7:35. The movie started at 7:35 P.M.

Exercise 9 – Gram or kilogram

  1. A strawberry is light, so use g.
  2. A bag of cat litter is heavy, so use kg.

Exercise 10 – Reasonable liters

A bathtub holds more than a bucket (10 L) but not as much as a swimming pool. The best choice is 150 L.

Exercises 11 and up

Exercise 11 – Add masses

\(240 + 365 = 605\). The total mass is 605 g.

Exercise 12 – Fill the beaker

The water is at 6 L. \(10 – 6 = 4\).

0246810L10 L
The dashed line marks 10 L, so 4 L more fill the beaker.

Exercise 13 – Compare masses

\(5 – 2 = 3\). The pumpkin has 3 kg more mass.

Exercise 14 – Read the scale

  1. The pointer is at 450, so the mass is 450 g.
  2. \(1{,}000 – 450 = 550\), so 550 g more are needed.
01002003004005006007008009001000g
The pointer shows 450 g.

Exercise 15 – Equal groups of liters

\(6 \times 2 = 12\). Ethan buys 12 L of juice.

Exercise 16 – Share kilograms

\(24 \div 4 = 6\). Each crate holds 6 kg.

Exercise 17 – Homework time

From 4:25 to 5:00 is 35 minutes. From 5:00 to 5:10 is 10 minutes. \(35 + 10 = 45\). Lia works for 45 minutes.

Exercise 18 – Two trips

Total travel time: \(25 + 15 = 40\) minutes. From 7:35, 25 minutes later is 8:00, and 15 more minutes is 8:15. Noah arrives at 8:15 A.M.

Exercise 19 – Jug of water

Poured: \(4 + 3 = 7\) L. Left: \(9 – 7 = 2\). There are 2 L left.

Exercise 20 – Crates of oranges

Total: \(4 \times 18 = 72\) kg. Left: \(72 – 25 = 47\). 47 kg are left.
