Question

Determine the average speed of a car that starts from ground zero and reaches 50km, for 1 hour

a) 20 km / h
b) 30 km / h
c) 50 km / h
d) 100 km / h

Answer 1

$\large\bigstar\bf\underline{Answer:}$

$\longrightarrow$ Option c) 50km/h

$\bigstar\bf\underline{Explanation:}$

$\longrightarrow$ Average speed = $\mathtt{\frac{Total\:Distance}{Total\:Time}}$

Let,

• Total distance be 50km
• Total time be 1 hour

$\longrightarrow$ Average speed = $\frac{50}{1}$

$\longrightarrow$ Average speed = 50km/h
