Arjun runs 8km everyday except on alternate Saturdays and Sundays when he runs 12km. How many kilometers does he runs in 2weeks?
Answers
Answer:
Arjun runs 120 km in 2 weeks
Step-by-step explanation:
Given that Arjun runs 8 kilometres everyday except on alternate Saturdays and Sundays, when he runs 12 kms
We need to calculate the kilometres run in 2 weeks.
In 2 weeks, lets first exclude alternate Saturdays and Sundays.
Thus, in span of 2 weeks, Saturday and Sunday will be considered only one
Number of days in 2 weeks = 14
Number of days in 2 weeks excluding Saturdays and Sundays = 14 - 2 = 12
Lets us first calculate the distance when Arjun runs 8 kilometres
Now, Distance run in 1 day = 8 kms
Distance run in 12 days = 8 × 12 = 96km
Now, distance when Arjun runs 12 kilometres
Arjun runs 12 km on 2 days, thus distance covered = 12 × 2 = 24 kms
Total kilometres run by Arjun in 2 weeks = (96 + 24)kms = 120 kms
No of days except Saturday and Sunday
=> 5
=> in two weeks 5 x 2
= 10
Total distance in these days = 8 x 10
= 80km
Saturday and Sunday in 2 weeks
=> 4 days
Distance in Saturday and Sunday = 4 x 12
= 48 km
Hence total distance is 80 + 48 = 128 km
