A car traveled a distance of 126 miles in 3 hours. Traveling at the same speed, what distance would this car travel in 7 hours?
Arte-miy333 [17]
First method: by the rule of three:
126 miles---------------------3 hours
x---------------------------------7 hours

x=(126 miles * 7 hours) / 3 hours=294 miles.

Answer: 294 miles.

Second method:
Speed=distance/ time           ⇒distance=speed x time

We calculate the speed of the car:
Speed=126 miles/3 hours= 42 miles/hour.

Data: 
Speed=42 miles/hour
time=7 hours

Distance=speed x time
Distance=(42 miles/hour)(7 hours)=294 miles

answer: 294 miles.

Your equation for the first point will be y=x+50

Explanation...

The x is zero so we just only put x. The y is 50 so we input a 50 giving us y=x+50.

Your equation for the second point will be y=2x+100.

Explanation...

Your slope is 2 so we input that and the y intercept is 100 giving us the equation y=2x+100.

Your equation for the third point will be y=4x+150

Explanation...

Your slope is 4 so we input that. Your y intercept is 150 so we input that. It gives us the equation y=4x+150.
