Answer 2

SOLUTION

TO DETERMINE

A bus travels 300 km in 6 hours.

a) How much time is required to cover 280 km with the same speed

b) Find the distance covered in 10 hours with the same speed.

EVALUATION

Here it is given that the bus travels 300 km in 6 hours

So the distance the bus travels in 1 hour

$\displaystyle \sf{ = \frac{300}{6} \: \: km }$

$\displaystyle \sf{ =50 \: \: km }$

a) Hence the time is required to cover 280 km with the same speed

$\displaystyle \sf{ = \frac{280}{50} \: \: hour }$

$\displaystyle \sf{ = \frac{28}{5} \: \: hour }$

$\displaystyle \sf{ = 5 \frac{3}{5} \: \: hour }$

$\displaystyle \sf{ = 5 \: \: hour \: \: 36 \: \: minute }$

b) The distance covered in 10 hours with the same speed

= ( 50 × 10 ) km

= 500 km
