Marks: +1, -0

Zakir travels from City A to City B. If Zakir drives his car at

\;{2}/{3}

of his normal speed, then he reaches City B 10 minutes late. Find the time (in minutes) that Zakir would have taken to travel from City A to City B if he drove at his normal speed.

Validate

Solution:

Let normal time

= t

minutes .
Time taken at

\;{2}/{3}

speed

=\;{ t }/{{2}/{3}}=\;{3 t }/{2}

Delay

=

Time at reduced speed - Normal time
Delay = 10 minutes
Calculation:

\;\;\text " Delay "\;=\;{3 t}/{2}-t

\;⇒ \;{3 t}/{2}-t=10

\;⇒ \;{3 t}/{2}-\;{2 t}/{2}=10

\;⇒ \;{t}/{2}=10

\;⇒ t=20
