Sec= 1/(cos), you can add or subtract 360 degrees from any angle measurement without changing the value of any of the trig functions i.e. 405 degrees= 405-360=45. cos of 45 is sqrt(2)/2 so sec405= 2/sqrroot2
The full length of the journey = 3150 miles
on the first day they completed = 567 miles
suppose 567 is x% of 3150 So
3150 x = 567
--------------
100
let us multiply both sides by 100 and divide both sides by 3150
x= 567 * 100
---------------
3150
x= 18
