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