If a car travels 40 km in 1 hour, how many kilometers will it travel in 7 hours at the same speed?
Correct: C
First, determine the car's speed: Speed = Distance / Time = 40 km / 1 hour = 40 km/h. Then, use the speed to find the distance traveled in 7 hours: Distance = Speed * Time = 40 km/h * 7 hours = 280 km.
