Answer:
d(4)=?
where
d= distance
t= hours
In this Linear function given by the law d(t) = 12t +20 and the graph below. To find the d(4), means to find out how many miles she cycled in the instant 4 hours.
By this function, after a break , the instant t=0, she had already cycled 20 miles.
Let's calculate
d(4) = 12(4) +20
d(4) =48+20
d(4)= 68 miles
