Answer:
Option 'b' i.e. -11/20 is the correct option.
Thus,

Step-by-step explanation:
Given the expression

Determining the difference of the fractions

The Least Common Multiplier of 5, 4 is 20. Thus, adjust the fractions based on the L.C.M.

Apply the fraction rule: 

Add the number: 4-15 = -11

Apply the fraction rule: 

Please check the attached figure, where the pointing-down arrow is representing the correct answer which is -11/20.
Therefore, option 'b' i.e. -11/20 is the correct option.
Thus,

Answer:
10 seconds.
Step-by-step explanation:
The velocity at which they are approaching each other = 59 + 41 = 1000 km per second.
Velocity = distance / time
So time = distance / velocity
= 1000 / 100
= 10 seconds.
On your calculator do 4/3 x pi (approx 3.14) x 4^3
so 4/3 x pi x 64
which is 85.33(2dp) x pi
i think you should get somewhere around 267.94 ish
