Question

If Sheela travels at the rate of 4 km/hr, she reaches the school 5 minutes late and if she
travels at the rate of 5 km/hr, she reaches the school 4 minutes too soon. How far is the
school from her home?​

Answer 1

Answer:

ur ans is here

Step-by-step explanation:

As speed = DIST / TIME

Let x be the time of her school so by equation

4kmph = DIST / (x+5)

I.e 4(x+5) = d …….(1)

As she was late 5 mins hence x+5

For 2nd case

6 KMPH= DIST / (x-10)

I.e 6(x-10)=d……(2)

As LHS are equal , hence

4(x+5)=6(x-10)

4x+20=6x-60

80=2x

X= 40
