Question

Peter roller skates with a constant speed of 8 km/h. How far can he travel in 3 hours 45 minutes​

Answer 1

Answer:

32 km/h

Explanation:

Answer 2

Answer:-

• Speed=8km/h
• Time=3hours 45minutes

$\\ \tt{:}\longrightarrow 3\dfrac{3}{4}$

$\\ \tt{:}\longrightarrow \dfrac{4\times3+3}{4}$

$\\ \tt{:}\longrightarrow \dfrac{15}{4}hours$

Now

$\boxed{\sf Distance=Speed\times Time}$

$\\ \tt{:}\longrightarrow Distance=8\times\dfrac{15}{4}$

$\\ \tt{:}\longrightarrow Distance=15\times 2$

$\\ \tt{:}\longrightarrow Distance=30km$
