thank @ms sue help me out this one also............The average age of 24 pupils is 15 years while the average age of 16 pupils is 14 years.What is average age of 40 pupils in a class?

(24 * 15) + (16 * 14) = ?

Divide your total above by 40 to find the average.

it comes 14.6 years do i suppose to write that answer or i should approximate to 15 years because there is no decimal or fraction years

I'd use 14.6

To find the total distance Marium will travel in 40 days, we first need to calculate the distance she travels in one day. Given that Marium travels a distance of 8 km to and from the school each day, we can calculate the total distance traveled in one day by multiplying the one-way distance by 2:

8 km/day * 2 = 16 km/day

Now that we know the distance Marium travels in one day, we can find the total distance she will travel in 40 days by multiplying the daily distance by the number of days:

16 km/day * 40 days = 640 km

Therefore, Marium will travel a total distance of 640 km in 40 days.
