A searchlight rotates

A searchlight rotates through one complete revolution every 4 seconds. How long does it take the light to rotate through 71 degrees?

Greg W.

I am using ratios to solve 1 rev/4 sec and 360 deg/1 rev Rev cancels leaving 360 deg/4 sec which is 90 deg/1sec Now using proportions 90 deg/ 1 sec = 71 deg/ x sec cross multiply and divide 90x = 71 x = 71/90 = .789 sec to rotate 71 deg
