Question

use the formula d=rt to find the distance traveled by a car driving at an average speed of 50 miles per hour for four and a half hours

Answer 1

As per problem, we have

Average speed of car =50 miles per hour.

Time =$4\frac{1}{2} hr$

Given formula to use is

$d=rt$

$\text{where d=distance traveled, r=Average speed, t= time}$

So, to find the distance traveled can be find by substituting the values in the above equation we get

$d=50*4\frac{1}{2}\\\\d=50*\frac{9}{2}\\\\d=25*9\\\\d=225 \ miles$

Hence distance traveled =225 miles.

Answer 2

Since she goes 50 mph for 4 and a half hours, we multiply 50 by 4 1/2

50 * 4 1/2 = 225

She travels 225 miles. Hope this helps!
