Answer:

4/5 of an hour

Step-by-step explanation:

3/10 of an hour (60 minutes) equals 18 minutes

3/4 of 5 km equals 3.75 km

therefore, you can create a ratio of minutes over km equals min over km

let 't' = time

18/3.75 = t/10

cross-multiply to get this equation:

3.75t = 180

divide each side by 3.75 to get:

t = 48 minutes

48 minutes out of 60 minutes equals 4/5 of one hour
