A train travels 68 kilometers in 2 hours, and then 64 kilometers in 3 hours. What is its average speed

skad [1K]

Average speed is the distance traveled by an object in total and divided by the amount of time an object covers the distance. The formula is -
Average speed = total distance traveled / total time taken
= 68km+64km / 2 hrs.+3hrs.
= 132km / 5hrs.
= 26.4km/hr.
Therefore, the train's average speed is 26.4km/hr.

withdrawals are when cash is taken out from the account

Flora withdraws an amount of $75 at a time from her bank account

she makes 7 such withdrawals

one withdrawal she takes out - $75

then seven withdrawals leads to - $75 x 7 = $525

then overall change in her account has been a net withdrawal of $525

so the overall change in the account is -$525
