Question

A bustravels about 400 milies between select the end mes could represent the estimated distance the use ENS 532 miles per hour for 774 hours 398 miles per hour for 1095 hours 476 milies per hour for hours O 76.3 miles per hour for 5.24 hours

Answer 1

Question:

Solution:

Remember the following formula for the distance of an object:

$v\text{ = }\frac{x}{t}$

where x is the distance, t is the time and v is the rate (velocity). Now, from the above equation, we can solve it for distance x:

$x\text{ = v. t}$

So replacing the data of each option we obtain the distance traveled:

First option:

$x\text{ = 53.2 x 7.74 = 411.76}\approx411.8\ne\text{ 400}$

then the first option is discarded: the answer is NO.

Second option:

$x\text{ =39.8 x 10.15 = 403.9}\approx404\ne\text{ 400}$

then the second option is discarded: the answer is NO.

Third option:

$x\text{ =47.6 x 9.8 = 466.48}\approx466.5\ne\text{ 400}$

then the third option is discarded: the answer is NO.

Fourth option:

$x\text{ =76.3 x 5.24 = 399.8}\approx400=\text{ 400}$

then the fourth option match. Then, the answer is YES.
