Question

Find the time in hours if speed is 60 km/hr and distance is 45,000​

Answer 1

Answer:

Time is 750 hours

Step-by-step explanation:

Speed = distance/ time

time = distance/ speed

       = 45000/60

      = 4500/6

     = 750 hours

Answer 2

Firstly we need to get the units in same system either cgs or SI

It is better to convert 60 km/h in m/s

For that multiply (60*5)/18 which is equal to 50/3 m/s

For time multiply 45 with 60 which gives us 2700 s

We have a formula which says

speed=distance/time

We calculated the speed and time is given to us

Putting the values in formula

(50/3)=distance/2700

Distance =(50/3)*2700

Which equals 45000m

Dividing it by 1000 we can get 45 km
