0.15
Step-by-step explanation:
Given expression
3 tenths- 3 twentieth
⇒

Therefore value of given expression is 0.15
Zane climb up in 33 seconds
44•33 = 1452 m.
so, Zane start from 1313 + 1452 = 2765 m below the edge.
to reach the edge with constant speed, Zane need 2765/44 = 62.84 seconds
we can round it to 63 seconds
Any number less than -3, so -3.5, -4, -5, -6, -6.35368, -7, etc.
Well, you have to simplify the bottom part to be able to answer it as a whole number. Hope this helps.
