Question

Meena cycles to her school at an average speed of 12km/hr and takes 20 minutes to reach school if she wants to reach her school in 12 minutes find her speed

Answer 1

First we have to take out the distance so...
$time \ \times speed$
we also have to convert time into hours so
$20 \div 60$
$12 \times \frac{1}{3}$
distance is 4 km.
Now to find her speed:
$distance \div time$
we first have to convert time into hrs.
time: 1/5
1/5 ÷4: 20km/hr
