will he take to cover 8000 meters?
91 Nivi covers 90 km in 2 hours 30 minutes. Find the speed in meter per second?

Answer 1

Answer:

Step-by-step explanation:

1) 8 minutes. 2)10 m/s

Explanation:

1) Speed of Vicky = 50 km per hour

His increased speed 50+10= 60km per hour

Means he cover 60km= 60000 meters in 1 hour i.e. 60 minutes

Hence He will cover 60000/60 = 1000 meters in 1 minute

So he will cover 8000 meters in 8 minutes

2)Distance Covered = 90km

Time taken = 2 hour 30 minutes = 2.5

hours

Speed ( in km/h) = 90/2.5 = 36 km/h

Speed (in m/s) = 36*5/18 = 10 m/s
