On a road trip maura drove at a speed of 60 miles per hour for the first two hours she then increased her speed by 25%
a- write an expression to show what her new speed is after the increase

Step-by-step explanation:

It does not matter for how long she was driving with the old speed if you only wanna know the new speed.

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

hope this
