Answer:
2 hours and 30 minutes.
Step-by-step explanation:
Katherine and Beatrice are 20 miles apart and they start to move towards each other.
It is given that Katherine runs at a constant speed of 5 mph and Beatrice walks at a constant speed of 3 mph.
As they are moving towards each other, so the resultant speed of them will be (5 + 3) = 8 miles per hour.
So, they will cover 20 miles distance with this 8 mph resultant speed.
Therefore, the time they will take to meet each other will be [tex]\frac{20}{8} = 2.5[/tex] hours i.e. 2 hours and 30 minutes. (Answer)
