A school cross country is 2 km 500 m long. Yuyo has already run 700 m. How far must she still run? Thandi has a pace of 32 m. How many paces would she have taken after walking 1 km? Bala walks 900 m t

$$1800 \text{ m} = 1 \text{ km } 800 \text{ m}$$

Yuyo must still run $\boxed{\text{1 km 800 m}}$.

:
Thandi has a pace of $32 \text{ m}$. How many paces would she have taken after walking $1 \text{ km}$?

$$\text{Number of paces} = \frac{\text{Total distance}}{\text{Pace length}} = \frac{1000 \text{ m}}{32 \text{ m/pace}} = 31.25 \text{ paces}$$

Thandi would have taken $\boxed{\text{31.25 paces}}$.

:
Bala walks $900 \text{ m}$ to school each day. How far does he walk to school and back?

$$\text{Distance to school and back} = \text{Distance to school} + \text{Distance from school}$$ $$\text{Distance to school and back} = 900 \text{ m} + 900 \text{ m} = 1800 \text{ m}$$

$$1800 \text{ m} = 1 \text{ km } 800 \text{ m}$$

Bala walks $\boxed{\text{1 km 800 m}}$ to school and back.

:
The school bus travels $18 \text{ km } 600 \text{ m}$ each day. How far does it travel in a school week?

$$93000 \text{ m} = \frac{93000}{1000} \text{ km} = 93 \text{ km}$$

The school bus travels $\boxed{\text{93 km}}$ in a school week.
