Sara is traveling home from a friends house. she drives 80 miles in 2 hours. if the total trip is 100 miles, how long will it take her to get home, assuming she travels at the same rate throughout her trip

It will take 2.5 hours.

Step-by-step explanation:

We know that,

If distance is 80 miles and time taken is 2 hours,

Then,

Here sara is travelling with the constant speed which is 40 miles per hour,

If distance = 100 miles,

Hence, the time taken by her =

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
