A boat sailed for 7 hours at the speed of 80 km/h. It changed its speed to 95 km/h for the next 6 hours. How far had boat sailed in km.

1130km

Explanation:

Initial Time taken by boat = 7 hours

Initial speed of boat = 80 km/h

New speed of boat = 95 km/h

New time taken by boat = 6 hours

Total distance sailed by boat = ?

Recall that speed is the total distance travelled divided by the total time taken.

i.e Speed = distance / Time taken

Distance = speed x time taken

So, from the data provided we will calculate the distance travelled in under the two conditions

In 1st case: distance = 80 km/h x 7 hours

distance = 560 km

In 2nd case: distance = 95km/h x 6hours

distance = 570 km

Hence, total distance = 560km + 570km

= 1130km

Thus, the boat had sailed 1130 kilometers far

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
