Question

It takes 1 3/4 minutes to wrap a parcel and a half a minute to address it. How long does
it take to wrap and address 30 similar parcels? ​

Answer 1

Answer:

From given:-

$13 \div 4 \times 60 + 1 \div 2$

=

$13 \times 15 + 30$

= 195 +30

=225 sec

Now for 30 parcels...

=

$225 \times 30 = 6750 sec$

or

$6750 \div 60 = 112.5 \: \: minutes$
