Respuesta :

3 km because 2 1/4 divided by 3/4 = 3

Answer: If they maintain the same pace for 2 hours they will go 6 km far.

Step-by-step explanation:

Hi, to solve this problem first we have to calculate the speed rate.

We have to apply the formula ⇒ speed = distance / time

2 1/4 km ÷ 3/4 h = 3 km per hour

Now that we have the rate, we simply have to multiply it by the time they will walk (2 hours) to calculate how far they will go.

2h x 3kmph = 6 km

If they maintain the same pace for 2 hours they will go 6 km far.
