Question 27094
relation between speed(s) ,time(t) and distance(d) is
d=s*t...since s=60 mph...d=60t......
d=480 miles..and s=60.mph....hence
480=s*t..........and........480=60*t
after 4 hrs d=60*4=240 miles
after 3 hrs d=60*3=180 miles
total distance =480 miles.
so remaining distance =480-180=300miles
