Question

How bad is the heavy​ traffic? You can walkwalk 1212 miles in the same time that it takes to travel 3232 miles by car. If the​ car's rate is 55 milesmiles per hour faster than your walkingwalking ​rate, find the average rate of each.

Answer 1

Speed by walking is 33 miles per hour

And speed of by car is 88 miles per hour

Step-by-step explanation:

We have given that it takes same time to walk 1212 miles as 3232 miles by car

Now let the speed by walk is x

As speed by car is 55 miles per hour faster than by walk = x+55

As time is same and we know that time is given as
`time=(distance)/(speed)`

So
`(1212)/(x)=(3232)/(x+55)`

`1212(x+55)=3232x`

`1212x+66660=3232x`

x = 33 miles per hour

So speed by walking is 33 miles per hour

And so speed of car = 33+55 =88 miles per hour
