Question

a 2 day automobile trip of 880 miles is planned. half of the distance is to be traveled each day at 55 miles per hour. how many hours will be driven each day

Answer 1

9 hours

Explanation:

Total distance for the two days = 880 miles

If half of the distance is to be traveled each day, then;

distance each day = 440 miles

speed of the automobile = 55 miles per hour.

Now, let's calculate the number of hours that will be driven each day.

Remember that;

speed = distance / time

=> time = distance / speed [substitute the values of distance and speed]

=> time = (440 miles) / (55 miles/hour)

=> time = 9 hours.

Therefore, the number of hours that will be driven each day is 9

Answer 2

Time travelled each day = 8 hours

Explanation:

total distance of 2-day trip = 880 miles

half the distance each day = 880 ÷ 2 = 440 miles

velocity travelled each day = 55 miles per hour

time travelled each day = ???

velocity = (distance trvaelled) ÷ (Time)

55 = 440 ÷ Time

`55=(440)/(Time) \\cross-multiplying\\55\ *\ Time = 440\\Time = (440)/(55) \\Time = 8\ hours`

∴ Time travelled each day = 8 hours
