Answer:
the time required is 4.5 mins
Step-by-step explanation:
The computation of the time that required to run home from school is shown below:
Given that as per the question
1 ÷ 6 km = 1 min
So,
1 km = 1 × 6
i.e.
1 km = 6 mins
Now to run 3 ÷ 4 km, the time required is
As we know
1 km = 6 mins
So,
3 ÷ 4 km = 6 × 3 ÷ 4
3 ÷4 km = 4.5 mins
Hence, the time required is 4.5 mins
