## To find out how long it will take to cover a distance of 100 km at the same speed, we can use the formula:

Time = Distance / Speed

Given that the car travels 60 km in 1 hour and 30 minutes, we need to convert the time to hours.

1 hour = 60 minutes

So, 1 hour 30 minutes = 1.5 hours

Now, let's substitute the values into the formula:

Time = 100 km / 60 km/h

Simplifying the equation:

Time = 1.67 hours

Therefore, it will take approximately 1 hour and 40 minutes to cover a distance of 100 km at the same speed.
