Answer 1

car travel a distance of 200.73km in 7/2 hours and 35/2 mimnutes

Answer 2

The distance is 206.64 kilometer.

Step-by-step explanation:

The speed of a car is $54\frac{1}{2}$ km per hour.

i.e. $\text{Speed}=54\frac{1}{2}=\frac{109}{2}\ km$

The time to travel is $\frac{7}{2}$ hours and$\frac{35}{2}$ minutes

Converting into hours,

$1\ min=\frac{1}{60}\ hr$

$\frac{35}{2}\ min = \frac{\frac{35}{2}}{60}=\frac{35}{120} \ hr$

$\text{Time}=\frac{7}{2}+\frac{35}{120}=\frac{455}{120}\ hr$

The distance formula is given by,

$\text{Distance}=\text{Speed}\times \text{Time}$

$\text{Distance}=\frac{109}{2}\times \frac{455}{120}$

$\text{Distance}=206.64\ km$

The distance is 206.64 kilometer.
