Answer 1

Hi friend,

Your answer is given below ....

100 Km is the actual distance

then it descended 11/10 km = 1.1 km

means 100 - 1.1 = 98.9 is the distance when it descended 11/10 km

then it ascended 3/5 km
we will add 3/5 (0.6) to 98.9 = 98.9 + 0.6 = 99.5 is the distance after it ascended 3/5 km

then again it descended 9/10 (0.9) = 99.5 - 0.9 = 98.6 is the distance when it again descended 9/10.

The current distance is 98.6 km.

Hope this helps you..☺☺☺
