We have arrived in Hanoi! How are you feeling?

Let's get some food. We are ordering phở and spring rolls.

phở: 60,000 VND

spring roll: 35,000 VND

(Hint: 60 + 35 = _ _ , 000)

Our first stop after Hanoi is Sapa. There are many mountains and small villages here. What do you think?

We drove 108 kilometers towards Sa Pa We still need to drive 211 kilometers to arrive. How far is Sa Pa from Hanoi? (How many kilometers do we drive in all?)

In Sa Pa, we went to Sun World. We decided to go in groups. There were 6 groups with 4 students in each group. How many students went to Sun World in all?

After Sa Pa, we traveled south to Ninh Binh. There were 4 empty boats at the river. Each boat can hold 5 people. Is there enough space for 24 kids?

On our way to Ho Chi Minh city, we stopped in Da Lat to see waterfalls.

Da Lat has the perfect climate to grow strawberries (a little bit cool) so after the waterfalls we stopped to get strawberry ice cream. Yum! There were 121 people waiting for ice cream. 35 people left. How many people are still in line?
