Question

Sara takes 15 minutes from her house to reach school on a bicycle. If the bicycle has a speed of 2 metres per second, calculate the distance between her house and the school.

Answer 1

Given

• Time = 15 min = (15 × 60)s = 900s
• Speed = 2 m/s

To Find

• Distance between the school & Sara's house

Formula Used

• Distance = Speed × Time

Therefore,

→ 900 × 2

→ 1800

Therefore, the Distance between Sara & her house is 1800 m

Additional Information

• The Actual Length of the path covered by a body during the whole journey is known as Distance
• Distance is a scaler quantity
• Rate of Change of Distance is known as Speed

Important Formulae

• Speed = Distance/Time
• v = u + at
• v² - u² = 2as
• S = ut + ½at²

Answer 2

1800m

Step by step explanation:

Time = 15 mins

= 15 × 60 secs

= 900 secs

Speed = 2 m/sec

=> Distance = Speed × Time

= 2 × 900 m

= 1800 m

∴ Distance between her house and school = 1800 m
