Distance = 600 m = 0.6 km.
Time = 5 minutes = 5/60 = 1/12 hour.
Speed = Distance/Time.
= 0.6 ÷ (1/12),
= 0.6 × 12,
= 7.2 km/h.
Time = 5 minutes = 5/60 = 1/12 hour.
Speed = Distance/Time.
= 0.6 ÷ (1/12),
= 0.6 × 12,
= 7.2 km/h.

We can solve it in this way;
First, divide 60 by 5, as 1 hour is 60 minutes.
So 60/5 = 12.
Now, multiply the quotient by 600m - 600 * 12 = 7200m or 7.2k.
