Step 1 (a): Use the formula for time. t = (d)/(v) where d is distance in miles and v is speed in mph. For Janet: d = 60 miles, v = 40 mph. t_J = (60)/(40) = 1.5 hours Janet's journey takes 1.5 hours. Step 2 (b): First find Bill's time. For Bill: d = 80 miles, v = 40 mph. t_B = (80)/(40) = 2 hours Difference: t_B - t_J = 2 - 1.5 = 0.5 hours Bill spends 0.5 hours longer driving than Janet.
