Salma takes 15 minutes from her house to | Class 7 Science Chapter Motion and Time, Motion and Time NCERT Solutions

Question:

Salma takes 15 minutes from her house to reach her school on a bicycle. If the bicycle has a speed of 2 m/s, calculate the distance between her house and the school.

Answer:

Speed = 2 m/s
Time taken to reach school = 15 minutes = 15 x 60 seconds
                                                                  = 900 seconds
Speed = Distance travelled
                         Time

Distance= speed x time
               = 2 x 900
               = 1800 m
Also, 1 km = 1000 m

Therefore, 1800 x 1/1000 = 1.8 km.
Hence, the distance between her house and the school is 1.8 km.
