Answer 1

Answer:

YOUR ANSWER IS 18KM

Step-by-step explanation:

Assume that he starts travelling to his workplace at the same time every day

Let the distance between his work place and home be 'd'

Let the actual time be 'x'

Distance = Speed * Time

Convert minutes into seconds as the units should be in kmph

As 24 kmph speed resulted in 5 minutes late, it is taken as increment 

d = 24(x + 5/60) ---------------(1)

As 30 kmph speed resulted in 4 minutes early, it is taken as decrement 

d = 30(x - 4/60) ----------------(2)

(1) and (2) are equal

=> 24(x + 5/60) = 30(x - 4/60)

=> 24x+2 = 30x-2

=> 30x - 24x = 2+2

=> 6x = 4

=> x = 2/3

Substitute the value of x in (1)

=> d = 24(2/3 + 5/60)

=> d = 24(9/12)

=> d = 18 km

The required answer is 18 km

Now,coming to the second part of your question it is bad driving at high speed as it can lead to injuries and in worst situations death.
