Question

I don't understand this word problem help!

Answer 1

Distance = 3/4 mile = .75 miles
rate = 3 (1/4) miles/hour = 3.25 miles / hour

Time = distance / rate
Time = .75 / 3.25
Time = 0.2307692308 Hours
= 13.8461538462 Minutes
= 13 Minutes and 50.7692307692 seconds
 

Answer 2

Distance from Apartment to Subway = 3/4 Mil or 0.75 Mi.

You walk at the rate (or your speed) = 3(1/4) Mi/h or 13/4 Mi/h (or 3.25 Mi/H)

Time needed = Distance/(Speed) = (0.75)/3.25 = (3/13) H

Or time I minute = (3x60)/13 = 180/13 = 13.846 ≈ 14 min
