Formula
Distance = rate x time
d = rt
Since you know the rate (60 mph)
to find the distance traveled in 3 hours
d = 60(3)
d = 180 Miles
Distganc traveled in 4 hours
d = rt
d = 60(4)
d = 240 Miles
distance traveled in 5 hours
d = rt
d = 60(5)
d = 300 Miles

a) The formula for calculating distance (d) is speed (s) *time (t)
In three hours at 60 mph, will result in 60*3 miles being covered=180miles.
b) In four hours at 60 mph, will result in 60*4 miles being covered=240miles.
c) d=st, as s =60, then d=60t
