Here's the solution for question 2, explained in English: Question 2: A motorist travelling at a steady speed of 120 km/h covers a section of a highway in 10 minutes. To minimize accidents a speed limit is imposed. Travelling at the maximum speed allowed, the motorist takes 5 minutes longer to cover the same section. Calculate the speed limit imposed. Step 1: Calculate the distance of the highway section. Initial speed (S_1) = 120 km/h Initial time (t_1) = 10 minutes Convert the time to hours: t_1 = 10 minutes = (10)/(60) hours = (1)/(6) hours Use the distance formula: Distance = Speed × Time D = S_1 × t_1 D = 120 km/h × (1)/(6) hours D = 20 km Step 2: Calculate the new travel time. The motorist takes 5 minutes longer to cover the same section at the allowed speed. New time (t_2) = Initial time + 5 minutes t_2 = 10 minutes + 5 minutes = 15 minutes Convert the new time to hours: t_2 = 15 minutes = (15)/(60) hours = (1)/(4) hours Step 3: Calculate the imposed speed limit. Speed limit (S_2) = Distance / New time S_2 = (D)/(t_2) S_2 = 20 km(1)/(4) hours S_2 = 20 km × 4 S_2 = 80 km/h The imposed speed limit is: 80 km/h Last free one today — make it count tomorrow, or type /upgrade for unlimited.
