Question

A boy walking at 3/5 of his usual speed reaches his school late by 14 minutes. Find the time he takes usually

to reach school at his normal speed.​

Answer 1

Step-by-step explanation:

normal speed =1

for 3/5 of normal speed 14 min late

normal speed = 1 × 3/5 ×14

= 0.6 × 14

= 8.4 units per minute

Answer 2

He usually takes 35 minutes to reach school at his normal speed.

Step-by-step explanation:

Let the speed usually be 'x'

So, new speed would be $\dfrac{3}{5}x$

So, late by 14 minutes,

According to question, it becomes,

$x-\dfrac{3x}{5}=14\\\\\dfrac{5x-3x}{5}=14\\\\\dfrac{2x}{5}=14\\\\x=7\times 5\\\\x=35\ minutes$

Hence, he usually takes 35 minutes to reach school at his normal speed.
