a person climbs to the top of the mountain at a rate of 1.5 kl/hr and down the same way at at rate of 4.5 kl/hr. If he was gone for 6 hours, how far did he travel from the top of the mountain ?

To find out how far the person traveled from the top of the mountain, we need to calculate the distance covered during the ascent (climbing) and the descent (coming down).

Let's begin with the ascent. The person climbs at a rate of 1.5 km/hr. Since he was gone for 6 hours, we can calculate the distance covered during the ascent by multiplying the rate by the time: 1.5 km/hr * 6 hr = 9 km.

Next, we move on to the descent. The person comes down at a rate of 4.5 km/hr. Similarly, we multiply the rate by the time: 4.5 km/hr * 6 hr = 27 km.

Now, to find out how far the person traveled from the top, we subtract the distance covered during the descent from the distance covered during the ascent: 27 km - 9 km = 18 km.

Therefore, the person traveled a total of 18 km from the top of the mountain.
