An object is traveling at a steady speed of 10 1 5 km/h. How long will it take the object to travel 1 4 5 km? First round to the nearest integer to find the estimated answer. Then find the exact answer.

Given that, the speed of the object, v= 1015 km/h.

The distance to be covered, d= 145 km.

Let, t, be the time to cover the given distance.

As, time = (distance)/(speed), so

t= 145/1015= 1/7 hours

So, the exact time is 1/7 hours.

As 1/7 hours=0.1428 hours (approximately), so the nearest integer is 0, when the time in hours.

As 1 hour = 60 minute, so

1/ 7 hour = 60/7 minute= 8.6 minutes.

The nearest integer, when the time is in minutes, is 7.

it would take 7/10 of an hour too fill the pool.
