You can put this solution on YOUR website!
Distance = rate x time
or
+d+=+r%2At+
--------------
You are given:
+d+=+50+ m
+r+=+45+ km/hr
----------------
First, you have to convert
meters to km
In terms of just units:
( m ) * ( km/m ) = km
+50%2A%28+1%2F1000+%29+=+.05+ m
-------------------------
Now units are compatible
+d+=+r%2At+
km = ( km/hr) x hrs
-------------------
+.05+=+45t+
+t+=+.05%2F45+
+t+=+1%2F900+ hrs
-----------------
Convert hrs to min
+%28+1%2F900+%29%2A60+=+4%2F60+
------------------------
Convert min to sec
+%28+4%2F60+%29%2A60+=+4+
-------------------
It takes 4 sec to travel 50 m at 45 km/hr
