Answer 1

Answer:

3. 24 is the right answer to this question

Answer 2

Answer:

T=0.2995 hr

Explanation:

Given that

Distance of office from ,d=10 KM

When she walk 0.5 KM:

Lets it take t time

We know that

Distance = Velocity x time

0.5 = 8 x t

t= 0.062 hr

When travel by bus:

So the remaining distance which she will cover by bus = 10 - 0.5 KM

 S= 10 - 0.5 KM = 9.5 KM

Speed of bus = 40 Kmph

Lets it take t' time

We know that

Distance = Velocity x time

9.5 = 40 x t'

t'=0.237 hr

So the total time T=t+t'

T= 0.237 + 0.062 hr

T=0.2995 hr

Time taken by her to reach the office is 0.2995 hr.
