How long does a car traveling at 70 mph take to travel 88 miles, in hours
dybincka [34]
So,

Obviously, the car will travel 70 miles in one hour.  So after one hour, the car will have traveled 70 miles.  That leaves 18 miles.

The time it will take for the car to go another 18 miles will be 18 divided by 70.
\frac{18}{70}

Simplify.
\frac{2*3*3}{2*5*7}
\frac{3*3}{5*7}
\frac{9}{35}

Divide.
≈ 0.25714

So a car traveling at 70 mph will take approximately 1.25714 hours or 1.26 hours to travel 88 miles.

A rectangular plot 72 metres long and 20 metres wide on a school farm sided into 18 equal plots. What the area of each plot?
marin [14]

Answer:

Step-by-step explanation:

There are many ways this could be done, but the simplest way is to divide 18 into 72. That gives 4. So each plot is 4 * 20 = 80 m^2

If you are willing to use fractions, the answer could be 20*72 / 18 = 8 * 10  which is more feasible and still gives 80, but the land may not permit it. However math will.

It's hard to give an exact answer when it is this open ended.
