Answer 1

140.4

Explanation:

Answer 2

In 2 hours car can travel 140.4 km with constant speed.

Solution:

As given the car can travel 351 km in 5 hours.

We know the speed of the car in one hour.

So the car travels in one hour
`\left((351)/(5)\right)` km = 70.2 km

Hence the speed of the car is 70.2 km/hour.

Now if the car travels with the same speed,

Then the in 2 hours the car can travel total
`(70.2*2)` km = 140.4 km
