✿ Quality answer needed​

Answer 1

Step-by-step explanation:

a)550/5-110km in one hour

110*7-770km in 7 hours

b)550/5-110km in per hour

3080/110-28 hours

Answer 2

$\huge\rm \underline \color{red}{required \: answer}$

We have,

a) Distance travelled by the car in 5 hours = 550km.

b) Distance travelled by the car in 1 hour = 550 km ÷ 5 = 110 km

Distance travelled in 7 hours = 110km × 7

= 770 km.

•°• Distance will the car covers in 7 hours is 770 km.

_________________________

b) Time taken to travel 550 km = 5 hours

Time taken to travel 1 km. = 5/550 hrs

= 1/110 km

Time taken to travel 3080 km = 3080×1/110

= 28 hours.

•°• hours needed to travel a distance of 3080 km if the car travels at a uniform speed is 28 hours.
