Answer 2

Correct Question :

• Ritu cycles to her school at an average speed of 12 km/h. It takes her 20 minutes to reach the school. If she wants to reach her school in 15 minutes, what will be the speed.

Solution :-

Required Formula :

• Distance = Speed × Time ( D = S×T).
• Speed =Distance / Time (S=D/T).

First step :

• Speed (S)=12 km/h
• Time(T) = 20/60 = 1/3 h

⇢ D = S×T

⇢ D = 12 × 1/3

⇢ D = 4 km

Second step :

• Distance (D) = 4 km
• Time(T) = 15 /60 = 1/4 h

⇢ S = D/T

⇢ S = 4/(1/4)

⇢ S = 4×4

⇢ S = 16 km/h

Hence, the required speed is 16 km/h.
