Given:
Distance to walk = ¾ mile or 0.75miles
Walking speed = 1 1/8 miles per hour or 1.125 miles per hour
Determine the time it would take to reach the distance.
Formula for time can be derived from the velocity formula.
v = d/t
t = d/v
Solution:
Substitute the given values of distance and velocity or walking speed to the the formula for time.
t = 0.75 mi / 1.125 mi per hour
t= 0.667 hours
In order to get the exact value of hours, we convert it to minutes since w e have a decimal answer. 1 hour is equal to 6 minutes, therefore will multiply 0.667 by 60.
t in minutes = (0.0667)(60)
t in minutes = 40
The time it would take to reach the distance is 40 minutes.
