Word Problem
A bridge is built across a river. One quarter of the bridge is over the left bank of the river and one third of the bridge is over the right bank. The river is 120 m wide. How long is the bridge?
Let's break it down step by step:
ReplyDeleteAlex wakes up at 6:35 AM.
Sam wakes up 45 minutes after Alex.
6:35 AM + 45 minutes = 7:20 AM.
Emma wakes up 20 minutes before Sam.
7:20 AM - 20 minutes = 7:00 AM.
So, Emma wakes up at 7:00 AM.
