Question

In car traveling at a speed of 60 km per hour over a distance of 50 km how much longer will it take to cover a distance of 70 km if the speed is maintained is maintained

​

Answer 1

Answer: 2/6 hours longer

Explanation:

If the car is traveling at a speed of 60 km per hour and covers a distance of 50 km, it would take approximately 50/60 = 5/6 hours.

To find out how much longer it would take to cover a distance of 70 km at the same speed, we can use the formula:

Time = Distance / Speed

So, the time it would take to cover a distance of 70 km at a speed of 60 km per hour is approximately 70/60 = 7/6 hours.

Therefore, it would take an additional 7/6 - 5/6 = 2/6 hours longer to cover a distance of 70 km at the same speed.

Answer 2

It will take an additional 20 minutes to cover a distance of 70 km at a speed of 60 km/h.

Step-by-step explanation:

To determine how much longer it will take to cover a distance of 70 km while maintaining a speed of 60 km/h, we need to calculate the time it takes to cover each distance. We can use the formula:

Time = Distance / Speed

For the first distance of 50 km:

Time = 50 km / 60 km/h = 5/6 hours = 50 minutes

For the second distance of 70 km:

Time = 70 km / 60 km/h = 7/6 hours = 70 minutes

To find the difference in time, subtract the time for the first distance from the time for the second distance:

70 minutes - 50 minutes = 20 minutes

Therefore, it will take an additional 20 minutes to cover a distance of 70 km at a speed of 60 km/h.
