Question

A car travels 15 1/10 miles in 1/3 of an hour. What is the average speed, in

Answer 1

Given:-

$\red{➤}\:$$\sf Distance \: travelled \: by \: Car= 15\dfrac{1}{10} miles$

$\quad\sf =\dfrac{10×15+1}{10}= \dfrac{151}{10} miles$

$\red{➤}\:$$\sf Time \: taken \: by \: Car= \dfrac{1}{3} \:hours$

To Find:-

$\orange{☛}\:$$\sf Average \: Speed \: of \:Car, \:in \: miles \: per \: hour$

Solution:-

$\underline{\tt{Formula\:Applied}}$

$\green{ \underline { \boxed{ \sf{Speed=\dfrac{Distance \:travelled}{Time \:taken}}}}}$

$\underline{\tt\pink{Putting \:Values-}}$

$\begin{gathered}\\\quad\longrightarrow\quad \sf Speed=\frac{\frac{151}{10}}{\frac{1}{3}} \\\end{gathered}$

$\begin{gathered}\\\quad\longrightarrow\quad \sf Speed=\frac{151×3}{10×1} \\\end{gathered}$

$\begin{gathered}\\\quad\longrightarrow\quad \sf Speed=\frac{453}{10} \\\end{gathered}$

$\begin{gathered}\\\quad\longrightarrow\quad \sf Speed=45\frac{3}{10} miles \: per \: hour\\\end{gathered}$

$\boxed{\sf{Speed \:of \: the \: Car = 45\frac{3}{10} miles/hour}}$

Answer 2

Step-by-step explanation:

Miles = 15 1/10

Miles = 151/10 miles

Hour = 1/3 hour

Av = 151/10 miles / 1/3 hour

Av = 151/10 × 3 / 1/3 × 3

Av = 453/10 miles / hour

Av = 45,3 mil / h
