Question

Tony is 1⁄2 mile ahead of Laura on a jogging

path. If Tony is running at 4 miles per hour, and
Laura is running at 6 miles per hour, how long
will it take Laura to catch up with Tony?

Answer 1

15 minutes

Explanation:

Let Tony is running x distance when Laura catch up him.

Then Laura is running x + 0.5 miles distance .

This motion takes the t time.

Using the equation of the motion ,

s = ut

s - Distance u - velocity t - Time

For Tony's motion

x = 4 × t --------*

For Laura's motion

x + 0.5 = 6 × t ------**

** - * --->

x + 0.5 - x = 6t - 4t

0.5 = 2t

t = 0.25 hours

t = 15 minutes

Answer 2

¼ hours or 15 minutes

Explanation:

let the time it will for laura to catch up with Tony be 't'

Distance = speed × time

Distance corvered by Laura in time (t) = Distance corvered by Tony in time (t) + Distance between Tony and Laura

6×t = 4×t + ½

6t = 4t + ½

2t = ½

t = ¼ hours or 15 minutes
