Question

Marta walked at 4.1 miles per hour for 0.85 hours. How far did she walk?

Answer 1

since her velocity or speed is 4.1 mile per hour
the distance traveled can be found using
d=vt
d=(4.1)(0.85)=3.485 miles
is our answer logical if she travels 4.1 miles in a single hour that means in less than an hour she will travel less than 4.1 which is true for our answer.
