Speed of car = 50 km/hr
Time taken = 30 min = 30/60 hr = 0.5hr
Distance to airport =>
Speed = Distance / time
50 = distance to airport/ 0.5
Distance 50*0.5 = 25km
Required time to reach airport is 25 min = 25/60 hr
Distance = 25 km
Required speed = distance / time
25/(25/60)
60 km/hr
Time taken = 30 min = 30/60 hr = 0.5hr
Distance to airport =>
Speed = Distance / time
50 = distance to airport/ 0.5
Distance 50*0.5 = 25km
Required time to reach airport is 25 min = 25/60 hr
Distance = 25 km
Required speed = distance / time
25/(25/60)
60 km/hr

50 (30/25) = 2*30 = 60
