Giving - easy one - must be correct and work is shown.

Explanation:

Let's calculate the time taken to drive at 100 km/hr

distance = rate*time

time = distance/rate

time = 160/100

time = 1.6 hours exactly

Do the same for when she drove at 90 km/hr

time = distance/rate

time = 160/90

time = 1.7778 hours approximately

Next, subtract the time values

1.7778 - 1.6 = 0.1778

The difference in time values is about 0.1778 hours.

The last step is to multiply by 60 to convert from hours to minutes.

0.1778*60 = 10.668

This then rounds to 11 minutes
