Question

A car is moving at an average speed of 3¹/⁹km/hr. How much distance will it cover in 5¹/⁷ hours?​

Answer 1

Speed of car = 3 whole $\dfrac{1}{9}$ km/hr

=$\dfrac{28}{9}$ km/hr

time taken to travel x km=5 whole $\dfrac{1}{7}$ hours

=$\dfrac{36}{7}$ hr

we know that, distance = speed ${×}$ time

or, x = $\dfrac{28}{9}$ ${×}$ $\dfrac{36}{7}$ km

or, x = 16 km

So. the car will travel 16 km in $\dfrac{36}{7}$ hours

Answer 2

Speed of car = 3 whole $\dfrac{1}{9}$ km/hr

=$\dfrac{28}{9}$ km/hr

time taken to travel x km=5 whole $\dfrac{1}{7}$ hours

=$\dfrac{36}{7}$ hr

we know that, distance = speed ${×}$ time

or, x = $\dfrac{28}{9}$ ${×}$ $\dfrac{36}{7}$ km

or, x = 16 km

So. the car will travel 16 km in $\dfrac{36}{7}$ hours
