Question

Sierra is taking a train to visit her family. she wants to travel at least 500 miles today. the train is traveling at a constant average speed of 62 miles per hour and has already gone 248 miles. which inequality can be used to find x , the minimum number of hours it will take sierra to travel at least 500 miles?

Answer 1

To find the minimum number of hours it will take Sierra to travel at least 500 miles, divide the remaining distance by the average speed of the train.

Step-by-step explanation:

To find the minimum number of hours it will take Sierra to travel at least 500 miles, we can use the formula time = distance/speed. In this case, the distance Sierra needs to travel is 500 - 248 = 252 miles (since she has already traveled 248 miles). The average speed of the train is 62 miles per hour. Substituting these values into the formula, we have:

time = 252 miles / 62 miles per hour = 4.06 hours

Therefore, the inequality that can be used to find x, the minimum number of hours it will take Sierra to travel at least 500 miles, is:

x > 4.06
