I believe the answer is 116.

23-8=15
8*15=120
sqrt2=4
the number 120-4=116

Melissa walked at a rate of 88 feet per minute. What was her approximate speed to the nearest tenth of a mile per hour?
GREYUIT [131]

Answer:

1.0 mph

Step-by-step explanation:

so there are 60 minutes in an hour

you need to find what her speed is per hour

right now it is per minute

so multiply her current speed by 60

88*60=5280

there are 5280 feet in a mile.

Her current speed is 1 mile per minute

rounded to the nearest tenth of a mile is

1.0 mph
