The speed of a train of a train 60 miles per in 2 hours the train will cover (blank) miles in 4 hours the train will cover (blank) miles. the train covered miles in 4 hours than it did in 2 hours

The speed of the train is 60 miles per hr ...

so in 2 hrs, it will cover (60 * 2) = 120 miles

and in 4 hrs, it will cover (60 * 4) = 240 miles

so the train covered 120 more miles in 4 hrs then it did in 2 hrs ... or the train covered twice as many miles in 4 hrs as it did in 2 hrs
