Question

A girl runs x metre in 20 minutes . How many metres does she run in 1 hour

Answer 1

Answer:

3x metres

Step-by-step explanation:

if, 20 minutes running = x m

then, 1 minute running = (x/20) m

then, 60 minutes running = (x/20)*60 m

then, 60 minutes running = (x/2)*6 m

then, 60 minutes running = (x/1)*3 m

therefore 60 minutes running = 3x m

Answer 2

Answer :

1 hour = 60 minutes

She run in 20 minutes =x metres

She runs in 1 minutes = x/20

she runs into 60 minutes x/20× 60

x = 60/20=6/2=3metre
