Let's solve the two problems shown in the image.

### First Problem (Weight in Stones):
You are asked to convert a weight of 89.5 kilograms into stones.

1. The conversion factors are:
   - \(1 \, \text{kg} = 2.2 \, \text{pounds (lb)}\)
   - \(1 \, \text{stone (st)} = 14 \, \text{pounds (lb)}\)

Let's first convert kilograms to pounds:
\[
89.5 \, \text{kg} \times 2.2 \, \text{lb/kg} = 196.9 \, \text{pounds}
\]

Now, convert pounds to stones:
\[
\frac{196.9 \, \text{pounds}}{14 \, \text{pounds/stone}} = 14.06 \, \text{stones}
\]

Rounding to the nearest whole number gives:
\[
14 \, \text{stones}
\]

### Second Problem (Total Length Run in Feet):
In a relay race, 4 people each run 400 meters, and you need to convert the total distance run by the team into feet.

1. The conversion factors are:
   - \(1 \, \text{metre} = 1.09 \, \text{yards}\)
   - \(1 \, \text{yard} = 3 \, \text{feet}\)

Let's first calculate the total distance in meters for the whole team:
\[
4 \times 400 \, \text{metres} = 1600 \, \text{metres}
\]

Now, convert meters to yards:
\[
1600 \, \text{metres} \times 1.09 \, \text{yards/metre} = 1744 \, \text{yards}
\]

Finally, convert yards to feet:
\[
1744 \, \text{yards} \times 3 \, \text{feet/yard} = 5232 \, \text{feet}
\]

So, the total length run by the team is:
\[
5232 \, \text{feet}
\]
