Question

The Johnson family is taking a car trip. They are driving at an average speed of 60 miles per hour. The graph shows their distance traveled over time. How long will it take the Johnson Family to travel 420 miles?

Answer 1

do 420 divided by 60, which gives you 7. so it will take 7 hours for the johnson family to travel 420 miles.

Answer 2

In this question the graph is missing but we have sufficient information to find the time Johonson's family will tae to travel the given distance.

The concept we are going to use is the relation between the speed distance and time to find the time .

Formula is given by

`Speed = (Distance)/(Time)`

This can also be rearranged to

`Time =(Distance)/(Speed)`

Now we can use this formula to find the time for Johonson's family

It is given that the Speed = 60 miles per hour

And also Distance = 420 miles

Using the formula above we get

`Time = (420)/(60)`

So

Time = 7 hours
