Two jets, A and B, leave the same airport at the same time. Jet A travels at 350 km/h and Jet B travels at 220 km/h. How far apart are the jets after 3 hours?

Step 1: Calculate the distance traveled by each jet after three hours.
The formula for distance is $D = S \times T$.
For Jet A:
Speed ($S_A$) = $350 \text{ km/h}$
Time ($T$) = $3 \text{ hours}$
Distance ($D_A$) = $350 \text{ km/h} \times 3 \text{ h} = 1050 \text{ km}$

For Jet B:
Speed ($S_B$) = $220 \text{ km/h}$
Time ($T$) = $3 \text{ hours}$
Distance ($D_B$) = $220 km/h \times
