Question 6 Rational Numbers Exercise 1.6

A car is moving at the speed of 40 \frac{2}{3} km / h. Find how much distance will it cover

in 9 / 10 hrs?

Given

Speed of a car =40 \frac{2}{3} km / h = 122 / 3 km / h

Distance covered in 9 / 10 hour can be calculated as follows:

Distance = (122 / 3) × (9 / 10)

= 366 / 10

We get,

= 36.6 km

=36 \frac{3}{5} \mathrm{km}

Therefore, the distance covered by the car in 9 / 10 hours is36 \frac{3}{5} \mathrm{km}
