Given:

A car arrived at a town at 15:06

Travelled for 4 1/4 hours

To Find:

Time at whch the car started this journey

Solution:

1 hr = 60 mins

Step 1:

Conver 1/4 hrs in minutes

60 x 1/4 = 15 minutes

Step 2:

Travel time is

4 1/4 hours = 4 hrs +  15 minutes

Step 3:

14 hrs + 60 minutes + 6 minutes  - (4 hrs +  15 minutes )

10 hrs + 51 minutes

10 : 51
