Question

In what time can Saloni cover a distance of 450 m, if she runs at a speed of 20 km/hr.?

Answer 1

Answer:

saloni's speed =20 km/hr=(20×185) m/sec=9/50 m/sec

Time taken to cover 450 m =(450×9/50) sec                                             =72 sec

                                             =72/60 min

                                             =1 1/5 min

hope this helps

Answer 2

Distance =450m=.45km

Speed=20km/h

Time =?

Time =Distance/Speed

Time=.45/20

Time=9/40h=9/40×3600=810sec

Hence,saloni will cover the distance in 810sec or 13min 30sec
