Rani covers a distance of 475 m in a minute. How much distance would Rani have covered in an hour if she travelled at 1.2 times of her current speed?
Answer & explanation
Correct answer: option 3
We know ,
Speed = \(\frac{DIstance }{Time}\)
= \(\frac{475 }{60}\)
New Speed = 1.2× \(\frac{475 }{60}\) = 9.5 m/sec
Time = 1 hour = 3600 sec
Distance = Speed × Time
= 9.5 × 3600
= 34200 m
= 34.2 km
So , distance covered is 34.2 km
