distance from city a to city b = 540 km
time taken b the car = 7 hours
speed at which 223 km was covered at = 80 km/h
time taken : 80 km/h = 223/x = 80/1 = 223/x
= 80x = 1 × 223
= 80x = 223
= x = 223/80
= x = 2.7875
remaining distance = 540 - 223 = 317 km
remaining time = 7 - 2.7875 = 4.2125
speed = distance/time
thus, speed = 317/4.2125
= s= 75.2522255
Therefore, the remaining distance was covered at the speed of 75.25 km/h
I think this is the answer, hope it helps :)
