Answer:
Distance = Speed × Time
= 10 × 40
Distance = 400 km
if speed is increased by 10kmph
New Speed = 40+10
New Speed = 50 kmph
but, distance remains the same
New Time = Distance/New Speed
New Time = 400/50
therefore, New Time = 8hrs

Answer:
8 hrs
Step-by-step explanation:
You can understand the distance is equals to the given formula
d=t*s
=10 hr * 40 km/hr
=400 km
Then let's find time if the speed is 50 km/hr
t=d/s
=400 km / 50 km/hr
=8 hr
