Question

Suppose you are driving to visit a friend in another state. you are driving 55 miles per hour. you must drive 440 miles total. if you have already driven 275 miles, how long will it take you to reach your destination? use h to represent the number of hours it will take to reach your destination. use the equation 55h + 275 = 440.

Answer 1

3 hours

Explanation:

What we are trying to solve:

55h + 275 = 440

Step:

55h + 275 - 275 = 440 - 275

Simplified:

55h = 165

Step:

55 ÷ 55h = 165 ÷ 55

Simplified:

h = 3

Therefore, 3 is the correct answer.

Answer 2

Time=(distance)/(speed)
speed=55 mi/hr
Total distance=440 miles
Distance covered=275 miles
remaining distance=440-275=165 miles
Time taken to cover the remaining distance will be:
time=165/55=3 hours

Total time taken to travel=440/55=8 hours
if we are to use the equation given by:
55h+275=440
time taken will be found by solving for h, thus we shall have:
55h=440-275
55h=165
h=165/55
h=3 hours

Answer: 3 hours
