Time Calculation and Interpretation

The video tutorial explains how to determine start and end times for various activities using number lines. It covers examples involving Andrey's science project, Amira's leaf raking, Scarlet's art club, Anna's reading session, and Mohamed's phone call. Each example demonstrates how to calculate the duration or end time based on given start times and durations.

If Andrey starts his project at 4:00 pm and works for 50 minutes, what time does he finish?

• 4:30 pm

• 4:50 pm

• 4:45 pm

• 5:00 pm

If Andrey's project starts at 4:00 pm, which number line mark represents 4:50 pm?

• First mark

• None

• Middle mark

• Last mark

Amira starts raking leaves at 2:30 pm and finishes 25 minutes later. What time does she finish?

• 3:00 pm

• 2:50 pm

• 2:45 pm
