Question

Riya takes 15mins to reach her school from her house on her cycle. If the distance between her house and home is 2km.calculate the speed​

Answer 1

Speed = 2m/s

Time taken to reach school = 15 minutes = 15 × 60 seconds = 900 seconds

Speed = (Distance travelled)/ (Time)

Distance = (Speed x Time)

= 2 x 900 =1800m

Also 1km= 1000m

Therefore 1800x (1/1000) = 1.8km.

The distance between her house and the school is 1.8 km.

Answer 2

Answer:

2.22m/s

Explanation:

S=d/t
1min=60sec
15min=60/1x15
900sec
1km=1000m
2km=1000/1x2
2000m
S=D/T
S=2000/900
S=2.22m/s
Thus, speed is 2.22 m/s
