with an average speed of 12 km/h. If she
wants to reach her school 8 minute earlier,
her speed should be:
(A)8 km/hr
(B)20km/hr
(C) 12 km/hr
(D) 15 km/hr​

Answer 1

Step-by-step explanation:

Speed = 12 km/hr

Time = 20m

Distance = Speed x Time

Distance = 12x20/60 km

Distance = 4km

A/Q, Time = 20-8 = 12m

Speed = Distance/Time

Speed = 4kmx60/12 = 20 km/hr
