Question

After driving 175 miles in the plains, car travles up a hill at 28 miles/hr. If the total distance covered in the plains and the hill was 273 miles. How much time was taken by the journey in ghe hills?

Answer 1

Answer:

3.5 hours was taken by the journey in the hills.

Step-by-step explanation:

Total of 273 miles.

In the plains, 175 miles.

The rest(x), on the hills.

So

175 + x = 273

x = 273 - 175

x = 98

98 miles in the hills, at the speed of 28 miles/hr.

To find the time, we can solve a rule of three.

1 hr - 28 miles

x hrs - 98 miles

$28x = 98$

$x = \frac{98}{28}$

$x = 3.5$

3.5 hours was taken by the journey in the hills.
