Answer:
I'm sorry I need points I'm stuck on a question
15+c=17.50
First you subtract 15 by 15 because you switch operations from adding to subtracting then you would put C under it
Second subtract 17.50 and 15 and that is 2.50 so C= 2.50
2a. speed= distance
---------------
time
60÷69 = 52.1739 miles per hour.
so for the next one with the airplane flies 296 km in 276 min is the same formula.
296/276 = 39.9839 mph.
I couldn't see the first question clear...sorry but apply same formula.
Hoping this will help you
