You can put this solution on YOUR website!

if s= speed, d= distance covered and t= timee taken:
s = d/t
40 = 30 / t
so, t = 30 / 40
so, t = 0.75 km

Remember: Speed=Distance%2Ftime---> S=d%2Ft
t=d%2FS=30cross%28km%29%2F40%28cross%28km%29%2Fhr%29
t=0.75hr ---> 0.75cross%28hr%29%2860mins%2F1cross%28hr%29%29=45mins
Thank you,
