1. Arun can walk 15 km in 3 hours. How far can he
walk in 4 hours?
​

Step-by-step explanation:

15/3 = x/4

if you multiply you get 3x= 4*15.

4 times 15 is 60, then divide by 3 to get 20

Arun can walk 20 km in 4 hours.

20 km.

Step-by-step explanation:

First, divide 15 by 3 to find out how many kilometers Arun can walk in a single hour.

15/3=5

To find out how far he can walk in 4 hours, multiply 4 by the number of kilometers he can walk in an hour, which is 5.

4x5=20

Therefore, Arun can walk 20 km in 4 hours.

Hope this helps you out and have a great day (^人^)
