Solution
Distance travelled by car= 15 km
Time taken = 20 minutes
Speed of car in km/h
Convert 20 minutes to hour
1 minute = 1/60 hour
Therefore, 20 minutes = 20/60 = 1/3 hour
Now, Speed of car = Distance / time
Therefore, Speed of car = 15 x 3 = 45 km/h
Time taken = 20 minutes
Speed of car in km/h
Convert 20 minutes to hour
1 minute = 1/60 hour
Therefore, 20 minutes = 20/60 = 1/3 hour
Now, Speed of car = Distance / time
Therefore, Speed of car = 15 x 3 = 45 km/h
