Step 3 of 4A Total distance travelled by the person with constant speed is, s-vt Equate the two equations. Substitute 77.8 km/h for 0.367 h for ,, 89.5 km/h for v. (77.8 km/h)(0.367 h +2)-(89.5 km/h)( 2) 28.55 km +(77.8 km/h),-(89.5 km/h) 2 (11.7 km/h) 2 28.55 km -2.44 h Find the total time of travel as follows: T 0.367 h+2.44h 2.807 h
