Answer :
Final answer:
The car covers a distance of 120 km in 90 minutes and takes 3 hours to travel 240 km at a steady speed of 80 km/h.
Explanation:
To find the distance covered by the car in 90 minutes, we first convert the time to hours. Since 90 minutes is equal to 1.5 hours (90 minutes / 60 minutes per hour), the car travels for 1.5 hours at a speed of 80 km/h. Multiplying the speed by the time gives us the distance covered: 80 km/h * 1.5 h = 120 km.To find the time it takes to travel 240 km at a speed of 80 km/h, we divide the distance by the speed: 240 km / 80 km/h = 3 hours.
