00:00This is question number 4 of exercise 1.3.
00:05In this question, Moomna walks 3.5 km per hour.
00:11She took a 12-hour walk.
00:13How far did she walk?
00:15Means in this question, the information provided to us is that
00:21Moomna has walked 3.5 km per hour.
00:28And how many hours did she walk?
00:32How much time did she take?
00:33That is 12 hours.
00:34And we have to know how far.
00:36How far means how much distance did she cover?
00:40How much distance did she travel?
00:42First of all, we will write her statements.
00:48Moomna walks 3.5 km per hour.
00:56Basically, it is her speed.
00:58She is walking at this speed.
01:00Time taken.
01:08Time taken by her is 12 hours.
01:13We have to know distance.
01:15How far.
01:16You have the formula of speed.
01:18Speed is equal to distance divided by time.
01:26Speed is already given to us.
01:29That is 3.5 km per hour.
01:33So, we will write speed here as 3.5.
01:36We do not know distance.
01:43And time is 12 hours.
01:46Now, we can write 1 below every number.
01:50We will do cross multiplication.
01:533.5 multiplied by 12.
01:57And 1 multiplied by distance.
01:59Basically, that is distance.
02:023.5 multiplied by 12.
02:06We will get 42.
02:09Basically, the distance is 42 km.
02:15Distance covered is 42 km.
