Speed=distance/time
40=d/10
d=400m
50=400/t
t=400/50
t=8hrs
40=d/10
d=400m
50=400/t
t=400/50
t=8hrs

Diatance = speed × time
D=40×10= 400kms
new speed = 50 km per hour
Time taken = distance /new speed
time = 400/50 = 8 hours
D=40×10= 400kms
new speed = 50 km per hour
Time taken = distance /new speed
time = 400/50 = 8 hours
