It won't just hand you the answer — it asks where you're stuck.How the checker works

Worked solution

1. Convert the travel time from minutes to hours

$\text{Time} = \frac{20}{60}\text{ h} = \frac{1}{3}\text{ h}$

2. Calculate the distance using the speed and time

$\text{Distance} = \text{Speed} \times \text{Time} = 66 \times \frac{1}{3} = 22\text{ km}$

Answer

$22\text{ km}$ (option 1)
