distance=40 km

new speed=(40×60)/25=96kmph

Answer 2

Answer:

GIVEN :

S = 80 KM/H

T = 30 MINUTES

D =?

S = D/T

D = S X T

D = 80 X 1/2

D = 40 KM

SPEED TO REACH HIME 5 MINS FASTER

D = 40 KM

D = 40000 M

T = 25 MINUTES

T = 1500 seconds

S = D/T

S = 40000/1500

S = 26. 66m/s

S =94.97 Km/H
