A train covers 240 km in 3 hours. Find its speed.

Step 1 — Write what is given

Distance = 240 km, Time = 3 h

Step 2 — Apply the formula

Speed = Distance ÷ Time = 240 ÷ 3

Step 3 — Answer

Speed = 80 km/h

Quick check: if the same train ran 4 hours at this speed, how far would it go?

320 km

Correct — well done.
