A car is traveling at a constant velocity. After two hours the car has traveled 110 miles. After four hours the car has traveled 220 miles. Assuming a linear equation fits this situation, find the linear equation for the given data.

y=45x+10
y=55x
x=55y
y=65x-10

If you want the linear equation from the above data, it is said that the car is travelling with constant velocity. So, it travels 110 miles in 2 hrs = 55 miles/hour. And from the second data you get 220/4=55 miles/hour. So, y may be considered as the distance traveled and x as the time taken.

igreen · Answer

2 hours = 110 miles

4 hours = 220 miles

Just graph them all..
