A can takes 20 minutes to cover a distance of
15 km calcolate its speed in km/hr

1 hour = 60 minutes.

20 minutes / 60 minutes = 1/3 of an hour.

20 minutes x 3 = 60 minutes = 1 hour

15 km in 20 minutes x 3 = 45 km per hour

Speed = 45 km/hr.

Step-by-step explanation:

Given:

Time = t = 20 mins = 20/60 = 0.33 hrs

Distance = S = 15 km

Required:

Speed = v = ?

Formula:

v = S/t

Solution:

v = 15 / 0.33

v = 45 km/hr

the 4th choice is the correct one
