My friend is 30 miles away from me and is travelling on the line passing through our two location at 60mph away from me.
how far is he from me after 3.7 hours?
: Can you give a linear equation that represents his distance from me as a function of time?
:
let t = travel time of your friend,
he starts out 30 mi away from you (t=0)
d = 60t + 30
when t = 3.7 hr
d = 60(3.7) + 30
d = 222 + 30
d = 252 mi after 3.7 hrs
