I’ll explain it in further detail for you.

First figure out the speed.

Speed = Distance (miles) /Time (mph)

Our units are per hour for this formula, so change it from minutes to hours.

180 minutes = 3 Hours

Speed = 210/3 = 70mph

Now we have to figure out how many minutes she has left to drive (time).

Time = Distance / Speed

280 Miles / 180mph = 1.555556 hours.

Now convert this back to minutes by multiplying by 60.

1.555556 x 60 = 93.3 minutes (93minutes)

The answer is 93 minutes
