To Find:
The time taken by Thoriso to get to school by walking.
Solution:
→ Thoriso can ride her bicycle at a speed of 5 km/h.
The time taken by Thoriso to get to school by Bicycle = 10 min = 1/6 hour
∵ Distance = Speed × Time
∴ The distance that Thoriso need to cover to reach school = 5 × 1/6
∴ The distance that Thoriso need to cover to reach school = 0.8 km
→ Thoriso can walk at a speed of 5 km/h.
∴ The time taken by Thoriso to get to school by Walking = 0.8/5 = 0.16 Hr
∴ The time taken by Thoriso to get to school by Walking = 0.16 Hr = 9.6 min
Therefore the time taken by Thoriso to get to school by Walking comes out to be equal to 9.6 minutes.
