a marathon race is 42.2km. what is the length of a marathon in meters? recall that 1000m= 1km.

42.2 * 1000 = ?

42.2 To find the length of the marathon in meters, we need to convert kilometers (km) to meters (m).

Given:

1 km = 1000 m

We are given that the marathon race is 42.2 km.

To convert km to m, we can use the conversion factor 1 km = 1000 m. By multiplying the given distance in km by the conversion factor, we can calculate the length of the marathon in meters.

Let's perform the calculation:

Length of the marathon = 42.2 km * 1000 m/km

Length of the marathon = 42,200 m

Therefore, the length of the marathon in meters is 42,200 m.
