Hi what Erica can run 16 1 6 of a kilometer in a minute. Her school is 34 3 4 of a kilometer away from her home. At this speed, how long would it take Erica to run home from school?

Answer 1

Answer:

the time required is 4.5 mins

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
