The speed 1.5 m/s is equivalent to speed of 5.4 km/h.
How to convert the unit of the speed?
The unit of the speed is calculated by applying the following formula as shown below.
The given speed to be converted;
v = 1.5 m/s
To be converted into kilometer per hour (km/h)
We know that;
1,000 m -----> 1 km
60 s ----------> 1 minute
60 minute ------> 1 hour
The speed is converted as follows;
= (1.5 m/s) x (1 km / 1000 m) x (60 x 60 s / 1 hr)
= [ (1.5 x 60 x 60 )/1000] (km/h)
= 5.4 km/h
Thus, the speed 1.5 m/s is equivalent to speed of 5.4 km/h.
