A Trip from Midrand South Africa to Makhado Town ( Louis Trichardt) South Africa which is approximately 400km. The name of the national road is N1 highway and it's a double lane road . There is 4 tollgate a along the way that you need to stop and pay. The legal speed limit is 120 km per hour and he claims to have started the trip at 3h30 am We have been arguing since last week that it is impossible to achieve 2h11 minutesPlease help

Therefore simply find the time by solving for T in the relation v = D/T => T = D/v = (400 km)/(120 km/h) = 3h. That's the shortest time it would take to travel 400 km at 120 km/h. Therefore if one doesn't stop for tolls it still couldn't travel 400 km in 2h11m.
