mike runs for 5 of an hour at a speed of 7.5 km/h and cycles for 15 minutes at 12 km/h.how far does he go

"mike runs for 5 of an hour "

Please clarify 5 (what) of an hour, it could be 5%, 5 minutes, or one-fifth, ...

To find out how far Mike goes, you need to calculate the distance covered while running and cycling separately, and then add them together.

First, let's calculate the distance covered while running:

Speed while running = 7.5 km/h
Time spent running = 5/60 hours (converted from 5 minutes to hours)

Distance covered while running = Speed * Time = 7.5 km/h * (5/60) h

Next, let's calculate the distance covered while cycling:

Speed while cycling = 12 km/h
Time spent cycling = 15/60 hours (converted from 15 minutes to hours)

Distance covered while cycling = Speed * Time = 12 km/h * (15/60) h

Now, let's add the distances covered while running and cycling:

Total distance covered = Distance covered while running + Distance covered while cycling

Plug in the values we calculated earlier:

Total distance covered = 7.5 km/h * (5/60) h + 12 km/h * (15/60) h

Simplifying the equation:

Total distance covered = (7.5 * 5/60) km + (12 * 15/60) km

Total distance covered = 0.625 km + 3 km

Total distance covered = 3.625 km

Therefore, Mike covers a total distance of 3.625 kilometers.
