Acar travels 351 km in 5 hours (with
a constant speed). how far can it
travel in 2 hours (with the same
speed)?

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 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 km = 140.4 km

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x
