With a speed of 57 km/h, Satya is able to complete his journey in 1 hour 20 minutes . If he wants to cover the same distance in 1 hour 16 minutes , then what should be his new speed (in km/h) ?

60

Distance = Speed × Time

Distance = 57 × (1 + \(\frac{20}{60}\)) = 57 × \(\frac{4}{3}\) = 76 km

Distance = New speed × New time

76 = New speed × (1 + \(\frac{16}{60}\))

76 = New speed ×(\(\frac{19}{15}\) )

New Speed = 60 km/h
