Lucie can walk about 3 4/5 miles each hour. about how far can she walk in 2 hours 45 minutes?

The first thing you should know is the following conversion:

1h = 60min

What you can do to solve the problem is the use of a rule of three:

60 - - - > 3.8

165 - - - > x

Clearing the value of x we have:

x = (165/60) * (3.8) = 10.45

x = 10.45 mi

answer

she can walk 10.45 mi in 2 hours 45 minutes
