Given :-

• A car travels 80 km in 2 hours

To find :-

• How much time is required to cover 140 km with the same speed?

Solution :-

• Distance travelled by car = 80 km
• Time taken = 2 hours
• As we know that

=> Speed = Distance/time

=> Speed = 80/2

=> Speed = 40km/h

• Therefore speed of a car is 40km/h

Now,

Distance travelled by car 140 km with same speed

• Distance = 140 km
• Speed = 40km/h

As we know that

=> Time = distance/speed

=> Time = 140/40

=> Time = 14/4

=> Time = 7/2 hours = 3.5 hours

Hence,

Time taken to cover 140km is 3.5 hours
