Answer:
150
Step-by-step explanation:
set up a equation-
4/5=120/x
x= people buying peanut butter.
120/4=30
30 x 5=150
2.27/0.03=75.6 repeating
You put the numbers into a mathematical equation (2.27÷0.03=). You then divide 2.27 by .03. Write the answer as 75.6 repeating.
.67×.3=.201
You first write the numbers into a mathematical equation (.67×.3=). Then you divide .67 by .3. Lastly you write the answer as .201.
Answer:
26.4 km/hr
Step-by-step explanation:
Sofia and Diego drive to work.
For Sofia
We convert miles to km
Sofia drives 72 miles in 1.5 hours.
1 mile = 1.6 km
72 miles = x
x = 72 × 1.6 km
x = 115.2 km
We find the speed in km/hr
Speed = Distance /Time
= 115.2km/1.5 hours
= 76.8 km/hr
For Diego
Diego drives 126 km in 2 hour 30 min.
Speed = Distance/Time
Time = 2 hour 30 min = 2.5 hours
Speed = 126km/2.5 hours
= 50.4 km/hr
The difference between their average speeds in km/h is calculated as:
76.8 km/hr - 50.4 km/hr
= 26.4 km/hr
