A car travels a distance of 550 km in 5 hours. What distance will the car cover in 9 hours?
How many hours are needed to travel a distance of 2750 kms?​

Answer 1

Step-by-step explanation:

$car \: traveled \: in \: 5 \: hours \: = 550 \\ car \: traveled \: in \: an \: hour \: = \frac{550}{5} = 110 \: km \: per \: hour \\ car \: traveled \: in \: 9 \: hours \: = 110 \times 9 = 990 \: km \\ time \: taken \: to \: cover \: 2750 \: = \: \frac{2750}{110} = \frac{275}{11} = 25 \: hours$
