Bob and John went for a walk if they were walking for 3/4 of an hour and they usually walk 5/2 a mile per hour how far have they gone

Answer 1

So far they have walked for 3/4 hours or 0.75 hours.

They usually walk 5/2 miles in an hour or 2.5 mph.

The easy way to solve this problem is to know what units are we looking for. The question asks how far they've gone so clearly we're looking for the answer in miles.

= (3/4 hours) * (5/2 miles per hour); here the hours units cancel out leaving the miles at the numerator unit.

= 15/8 miles or 1.875 miles is the distance Bob and John walked so far.
