I can travel at nearly 100 miles per hour, but never leave the room. You can cover me up, but that doesn’t slow me down. You will not know if I come only once or again and again and again. What am I?
I drive at an average speed of 30 miles per hour to the railroad station each morning and catch my train. On a particular morning, there was a lot of traffic and at the halfway point, I had averaged only 15 miles per hour. How fast must I drive for the rest of the way to catch my train?
A car has travelled 45 miles at 70 mph.
It started its journey with eight gallons of fuel but its tank has been leaking throughout the journey and is now dry.
The car completes 30 miles per gallon.
How many gallons of fuel does it leak per hour?
If an electric train is going 150 miles per hour north and the wind is blowing the same south, which way does the smoke blow?
