You can put this solution on YOUR website!
+d+=r%2At+
First, you can convert the time from
9 min 25 sec to hours
----------------------
Convert 25 sec to minutes
[ min ] = [ sec ]x[ min/sec ]
+25%2A%28+1%2F60+%29++=+.4167+
-------------------------
Convert 9.4167 min to hrs
[ hrs ] = [ min ]x[ hrs / min ]
+9.4167%2A%28+1%2F60+%29+=+.15694+
---------------------------
+d+=+r%2At+
[ km ] = [ km/hr ]x[ hrs ]
+d+=+32%2A.15694+
+d+=+5.022+
The distance from school is 5.022 km
-------------------
check:
+5.022+=+r%2A.15694+
+r+=+5.022+%2F+.15694+
+r+=+32.001+ km/hr
OK
