km/hr. How fast would a second carb
travelling if it leaves Jaipur an hour late
and overtakes the first car at 5 p.m.?​

Answer 1

Answer:

Speed of first car =50kmph

Time duration between 11 am and 5 pm =6 hours

Distance =50×6=300 kms

Let speed of second car be 's' kmph

As second hour leaves one hour later, hence it will travel 300 kms in 5 hours

Speed =

300

=60 kmph

Hence speed of second car is 60 kmph.
