Johnny's home is m miles from school. Johnny runs to school at a speed of 8 mph and then walks home from school at half that speed. How long does it take Johnny to run to school?

Answer 1

The time it takes Johnny to run to school can be found by dividing the distance by the speed: time = distance / speed.

Given that Johnny's speed is 8 mph, the time it takes him to run to school is: time = distance / 8.

However, the distance from Johnny's home to school is given as "m" miles, so the time to run to school is: time = m / 8.

So, it takes Johnny m / 8 hours to run to school.
