Answers
Step-by-step explanation:
Given:-
A car covers a certain distance at speed of 50km/hr in 13 minutes
To find:-
To cover the same distance in a minutes, it must travel at a speed ___km/hr.
Solution:-
Speed of the car = 50 km/hr
Time taken for the distance = 13 minutes
We know that 1 hour = 60 minutes
1 minute = 1/60 hours
=>13 minutes = 13/60 hours
We know that
Distance = Speed × time
=>Distance = 50×13/60
=>Distance = 650/60 km
=>Distance = 65/6 km
The car travels 65/6 km in 13 minutes at the speed is 50 km/hr
Now
Given that
Time taken for the same distance 65/6km = a minutes
=a/60 hours
Now Distance = Speed × time
Speed = Distance /time
=>Speed of the car = (65/6)/(a/60)
=>(65/6)×(60/a)
=>(65×60)/(6×a)
=>65×10/a
=>650/a km /hr
Answer:-
The speed of the car for travelling the same distance in' a 'minutes = 650/a km/hr
Used formulae:-
- Distance = Speed × time
