------------------------------------------------ If a car travels at a constant speed and covers 360 km in 8 hours, what distance will it cover in 15 hours? Also, find the time taken to travel 315 km.

A) 675 km, 11 hours
B) 450 km, 10 hours
C) 540 km, 12 hours
D) 600 km, 14 hours

Answer :

Final answer:

A car traveling at a constant speed of 45 km/h will cover a distance of 675 km in 15 hours. It will take 7 hours to travel a distance of 315 km. None of the above options are correct.

Explanation:

To find the distance a car will cover in 15 hours, we can use the formula: distance = speed x time. Since the car is traveling at a constant speed, we can use the formula to find the distance it will cover: distance = 360 km / 8 hours = 45 km/h. Therefore, in 15 hours, the car will cover: distance = 45 km/h x 15 hours = 675 km.

To find the time taken to travel 315 km, we can rearrange the formula to solve for time: time = distance / speed. Substituting the given values, we get: time = 315 km / 45 km/h = 7 hours.
