given:
t=+1+%281%2F4%29h=1.25h
average speed of s=800+%28m%2Fmin%29 .....convert into km%2Fh
800m=%28800%2F1000%29km=0.8km
1min=%281%2F60%29h+
so, s=0.8km%2F%281%2F60%29h=0.8%2A60%28km%2Fh%29=48%28km%2Fh%29
d=distance
d=s%2At
d=48%28km%2Fh%29%2A1.25h
d=48%28km%2Fcross%28h%29%29%2A1.25cross%28h%29
d=48km%2A1.25
d=60km
