Question

Debra can run 1/9 of a km in a minute. Her school is 13/3 km away from her home. At this speed, how long would it take Debra to run home from school?​

Answer 1

Answer:

39 minutes

Step-by-step explanation:

Debra goes 1/9 Kms in 1 minute

so for 1 Kms Debra takes 1/(1/9) = 9 minutes

now, her school is 13/3 Kms away from her home,

so she can cover 13/3 Kms in 13/3×9 = 13×3 = 39 minutes
