Her present age would be 5 because 4m=m+5 which would then turn into 3m=15 because you would subtract the m from both sides and end up with 3m+15, then you would divide 3 to both sides which would then give u an answer of m=5

Thomas decided to take the plane to save some time. Unfortunately, the plane was delayed for 1 5/6 hours. How long did the trip
seraphim [82]

Answer:

<u>Finally, the trip of Thomas will take an hour and fifty minutes more than the normal time it usually takes.</u>

Step-by-step explanation:

1. Let's check all the information provided to answer the question:

Time of Thomas flight delay = 1 5/6 hours

Time of normal flight = x hours

2. How long did the trip finally take?

For calculating how long the trip finally took, we need to do the following sum:

Time of normal flight + Time of delay

Like we don't know the time of the normal flight, we will define it as x, then:

x + 1 5/6 hours

x + 1 hour and 50 minutes ⇒ 5/6 of an hour = 5/6 * 60 minutes = 50 minutes

<u>Finally, the trip of Thomas will take an hour and fifty minutes more than the normal time it usually takes.</u>
