Answer:

m = 57t, where the units of measurement of 57 are mph and that of t is hr.

Step-by-step explanation:

Use the given info to find the speed of the train, which is a unit rate:

95 miles 95 mi

------------------ = ------------- = 0.95 mile/min

1 hr 40 min 100 min

Better yet, use hours, not minutes.

95 miles 95 mi

------------------ = ------------- = 57 mph

1 hr 40 min 1 2/3 hr

Then m(t) = (rate)(time) = (57 mph)t This corresponds to Answer D.
